Why can't humans walk through objects if the atoms in your bodies are mostly empty space?
Because the outsides of all atoms are negatively charged so they repel when they come close.

Answer . Think of it as the planets being the electrons: Earth, Venus, Mars etc.... and the Sun being the nucleus. The size of the Sun and planets relative to the empty space in the solar system is small. It's the same kind of idea with atoms.
The demonstration where radiation particles are shot into a gold page and most atoms stay in a straight line but a small fraction are deflected in all direction.
When the space inside an atom is described as "empty," what that refers to is mass. Most of the mass of the atom is concentrated in the tiny center, the nucleus. So most of the space inside the atom is devoid of mass. However, that does not mean there is nothing inside the atom. The "empty space" inside an atom is not actually empty. It is filled with extremely strong electric fields produced by the positive nucleus and the negative electrons. These fields interact with the electromagnetic radiation that corresponds to visible light. This interaction makes it impossible for light to travel through most atoms without being absorbed or deflected. Therefore, you can't see through most substances.
They are mostly empty space apart from the protons and neutrons in the middle of the atoms and tiny electrons in the electron cloud.
To say there is nothing there is simillar to saying water has no taste. There is something there, though we have yet to observe or define it.
In Rutherfords gold-foil experiment Rutherford concluded that the atom is mostly empty space with a small massive positvley charged center because?
When the beam of electrons passed through the gold foil, some weredeflected at odd angles. This indicated the presence of a moremassive portion of the atom that could be explained by the raisinpudding model.
The atoms that constitute your body are mostly empty space and structure such as the chair youre sitting on are composed of atoms that are also mostly empty space So why dont you fall through?
I'm not sure...I would go with: the atoms in the chair are strong, so empty space is less important because of the weight distribution. Also, my guess would be that the empty space is mainly in an area that doesn't support your weight.. The newest theory to answer this is applied to "How do the stars and planets hang where they are?" See: Dark matter. It is believed now that it is dark matter that holds things together. . I was watching a show on National Geographic that mentioned atoms being mostly empty space. They asked this question but in the context of a batter hitting a ball. The nucleus of an atom is enveloped by electrons which repel other electrons. They also said that because of this, nothing can actually ever touch: there is always a slight gap between objects. The sensation of touch is actually you feeling the repulsion of the electrons. . EDIT: From what I understand the ratio of empty space to solid space between the nucleus of an atom and it's electron is almost an exact ratio in size and distance of the Earth to the Sun. The electron's rotation is what keeps two objects separate. However, if something were vibrating at an entirely different frequency from another thing, it would be capable of passing right through it. The speed of the electron is so extreme that even light is reflected off of it's surface making an object appear to be solid. There are many theories involving alternate dimensions and realities that vibrate on other frequency ranges, exist at the same time and place as we do, but never affect our reality.
The experimental evidence led Rutherford toconclude that an atom is mostly empty space because most of theparticles weren't deflected off of the gold foil in hisexperiment. .
Sound is one example of a mechanical wave. Others are waves inwater, and waves along strings and ropes. All of these need material stuffto move through. If there's no material stuff, these waves don't goanywhere. There is no material stuff in space to carry mechanical waves.
Ernest Rutherford discovered that atoms contain mostly empty space, with his gold foil experiment. Bhor discovered that the electrons are not randomly placed around the nucleus.
because they are so small and so close together that there is no humanly known way to manufacture objects small enough to pass through these extremely small spaces.. So the empty space is not easy to get into. Atoms have a central nucleus and electrons whizzing around the nucleus in extremely fast orbits. Sometimes there are several layers or 'shells' of orbiting electrons. The whole structure is held together by strong forces, bot easily broken. Scientists have only recently been able to split to atom, but is has taken a lot of power snd scientific expertise. Furthermore, individual atoms are bonded to other atoms, making a very strong element or material, which holds together and which prevents other atoms from passing through.

\nNo matter where the atoms are the size of the atom and the distance between them is so small that a number or comparison would nothing to you and I.
Experiments by Thomas Rutherford demonstrated that alpha particles traveled through a gold filament with only slight deflection except for the rare particle that got deflect through extreme angles. The model that was devised to explain this was something mostly empty space with a dense center.
Yes. In 1908, Rutherford conducted an experiment of shooting a beam of alpha particles through a sheet of tinfoil. Most of the alpha particles went straight through the foil, which proves that there are empty spaces in atoms. And the rest of the particles that didn't go straight through the foil are deflected at acute angles, those particles are deflected by the positive nucleus in the center of the atoms.
Yes in fact Ernest Rutherford discovered that atoms contain mostly empty space, with his gold foil experiment. He discovered that the electrons are not randomly placed around the nucleus. Read more: http://wiki.answers.com/What_scientist_said_atoms_contain_mostly_empty_space#ixzz17NE5I4gI .

That's quite true. I have seen the amount of space in an atom that's occupied by the nucleus compared to the amount of space in the state of Texas that's occupied by a bunch of grapes.
Yes, this is essentially true. Well over 99.9% of the mass of any atom is in the nucleus. The electrons in their orbitals around that nucleus actually determine the spacial volume that the atom occupies. And on an atomic scale, the distance from the nucleus to the outer boundaries of the electron cloud is enormous. The atom is mostly empty space, and, therefore, anything made up of atoms is mostly empty space.
not exactly. it is mostly empty space- about 99.99...%. but at the centre of the atomic structure, there is a nucleus which contains nucleons (protons and neutrons). incredibly small electrons circulate around the nucleus, but their mass is negligible- about 1/2000 the mass of a proton..
Atoms are mostly empty space and structures such as a floor are composed of atoms and are therefore also empty space So why don't you fall threw the floor?
The atoms in a solid are tight and closely compacted together. They aren't liquid, whose atoms are looser than atoms in a solid; nor are they a gas, whose atoms are a LOT looser and spacious.
Sound waves are mechanical waves, NOT electromagnetic waves. Mechanical waves need a substance to pass through, that is, they need some sort of surface to vibrate against to send compression waves through to the surrounding air. Electromagnetic waves however may travel through empty space as they have no need for a surface, instead, they need only electric and magnetic fields that are present in empty space to pass through. (vibrating electric fields will, in turn, vibrate the magnetic field, which will then trigger a nearby electric field to vibrate, which will make another magnetic field to vibrate, and this is how electromagnetic waves may travel through empty space, but mechanical waves may not)
In Rutherfords gold foil exepirement Rutherford concluded that the atom is mostly empty space with a small massive positivley charged center because?
In Rutherford's gold foil experiment Rutherford concluded that the atom is mostly empty space with a small massive positively charged center because most of the electrons passed through but a few were wildly deflected.
Any form of energy that requires a physical medium to move from place to place could not propagate in empty space. An obvious example is sound energy.
Most of the particles went through the gold foil, but only a few bounced back.
First he took gold and made a sheet that was absurdly thin. Gold is soft and doesn't fall apart easily so it was ideal for this purpose. Then he used a known method of producing alpha particles(which are actually nucleus's of helium we found out later), and shot them at the gold foil. in a nearly complete circle around the gold foil he had detectors for this "radiation" (he had an opening where the radiation gun was). nearly all of the "pellets" went straight through the foil without any damage to it or distortion to the particles. A few seemed to bounce off, as they were detected behind the foil and more or less random. He said that this rebound was like a 6 inch artillery shell being fired at a sheet of tissue paper and for it to come straight back. He then put forward the idea of nucleus's and empty space 'as the fly in the cathedral' which overturned the previous nugget theories (and a bunch of others).
Actually this is true. The nucleus of an atom makes up a very small percentage of the atom (to be safe I am going to say less than five percent at largest.) The rest of the atom is composed of the electron orbitals. Since there can only be so many electrons in a single orbital at any given time most of the space in the orbital is never filled. Thus a large majority of an atom is indeed empty space.
Because of the vibration of matter. Billions of atoms are densely packed together to make a solid, and they're all constantly moving and vibrating, giving you the impression it's completely solid when in reality there is some empty space. However if you get into quantum theory you start to get ideas that suggest that if you sit in one place long enough you have a probability of just phasing right through it, which is kind of silly at first, but mathematically possible.
In some models, an atom is mostly empty space, as most of the mass is concentrated in the nucleus, which takes up a tiny proportion of the overall volume, whilst electrons are confined to specific orbits around it. However, the nucleus itself is not empty space, being made up of densely-packed protons and neutrons, which in turn are made up of smaller entities called quarks.
The electrons are repelled by the protons, which causes then to be farther away. If the nucleus was the size of a marble, then the atom would be the size of a football stadium. Correction: Electrons are not repelled by the protons but are attracted to them. Opposite charges attract.
Yes, this was proven by the Geiger-Marsden experiment (also known as the gold foil experiment).
Mostly empty, In the common model of the atom, electrons are really tiny and they are relatively far from the nucleus which is small (but larger than electrons). In between there is nothing. To bring this distance into perspective if a nucleus is here the next electron would be a football field away.
In rutherfords gold foil experiment he concluded that the atom is mostly empty space with a small massive positively chargeed centrer because?
Because most of the particles passed straight through the foil, some were slightly deflected and a few were bounced back.
The electrical resistance between subatomic particles is farreaching from the atomic nucleus and electron cloud. Electrons arealso moving very fast. The probability cloud that determines wherethe electrons could be, the orbitals and the nucleus itself, arestill not solid objects. Keep in mind under are current scientificunderstanding, no particles are "solid", they are anelectromagnetic force.
The electromagnetic and strong nuclear forces are very powerful andrepulsive at close ranges. Put two atomic nuclei near each otherand they will push away from each other. Similarly if you put twonegatively charged particles near each other they will also repelat very close distances.
While electromagnetic waves can travel though the vacuum of space, we know that mechanical waves like sound or seismic waves cannot travel except through a physical medium.
How the results of Ernest Rutherfords goldfoil experiment showed that the atom is mostly empty space?
Under the prevailing plum pudding model of thomson, the alpha particles should all have been deflected by, at most, a few degrees; measuring the pattern of scattered particles was expected to provide information about the distribution of charge within the atom. However it was observed that a very small percentage of particles were deflected through angles much larger than 90 degrees. This led them to conclude that most of the space in an atom was empty and the charge is concentrated at very tiny space.
well solids would be particuls all compact then liquads would be less compact and so on for gases... this usually occurs from van der walls forces breaking from heating and then there is just empty space between particles that are in a gas form
Who discovered that atoms are made up mostly of empty space and have orbitals on which electrons orbit the nucleus much like the layers of an onion?
Ernest Rutherford discovered atoms were mostly made of empty space by the his experiment in which he fired radiation particles at a thin gold foil, scoring only one hit in 8000 attempts. The planetary model of the atom was suggested by Hantaro Nagoaka in 1904 (later dubbed the Saturnian model), but was incorrect. and later, Nagoaka, himself abandoned this idea. I n 1911, Rutherford proposed a model that was better but also not viable. In 1913, Niels Bohr postulated a planetary model , but for totally different reasons. Bohr's hypothesis was incorrect also, but much closer to the truth. Bohr's model is still taught to students, in preparation for studies in quantum mechanics, where they get a much more realistic, and much more complex view of atomic structure.
Only a small percentage of alpha particles shot at the gold foil were deflected proving that except for the nucleus, the atom was mostly empty space.
Conduction requires the presence of matter. The way conduction works, one atom or molecule bumps into another one, transferring heat energy.
Rutherford's Experiment In this expt, Alpha particles (Double positive charged helium atom) were bombarded on a thin gold foil. Observation:- 1) Most of the rays passed straight through it without any deflection...(Answer to ur question) 2) Some rays were deflected through an small angle giving the sense of presence of Electrones 3) 1 out of 20000 rays was was deflected right back through the same path ( Nucleus )
Ernest Rutherford, with his famous gold foil experiment. The same experiment also proved that atoms have small, dense, positively charged nuclei, and that the electrons are outside the nucleus.
Which particular observation of Rutherford do you think him to believe that the atoms is mostly empty space and that its mass is concentrrated in apositve nucleus?
The fact that the vast majorityof the alpha particles got straight through led Rutherford topropose that the atom was composed primarily of empty space. The fact thatbackscattering occurred in 1 in 8000 alpha particles indicated thatthere was a small massive positively charged nucleus in the centreof the atom.
All atoms are mostly empty space, as the electromagnetic repulsion between atomic nuclei keep them from reaching each other (except under extreme pressure, as in the center of stars).
There simply isn't enough space for your atoms to pass through the atoms of a solid object. You can swim in water and walk through a gas because the particles are so spread apart, but you cant walk through solid objects because the particle configuration is extremely dense.
About 99.9% of the mass of an atom is concentrated at the nucleusof an atom. Electrons around the atom have really small mass inrelation to the protons and neutrons therefore their masses arenegligible. Therefore except for the nucleus, most space of an atomis just vacuum.
The alpha particle scattering experiment by Ernest Rutherford (1911) demonstrates that more than 99.9% of an atom contains empty space.
Yes, the nucleus is about the only space that the atom has, but is roughly is 10,000 times smaller than the whole atom. A theory is that everything we see is just an illusion.
The experiment you're asking about was performed by ErnestRutherford, and it's one of the most important experiments in ourquest to understand the nature of atoms. We call this experimentthe gold foil experiment. What Rutherford did was shoot alphaparticles, which are just charged helium atoms, at thin gold foil.Most of the alpha particles passed right through the gold foil.Some of the particles would deflect by a small angle. Occasionally,though, some of the particles would shoot back at the alpha emitteror off at a sharp angle. Before this experiment one of the morepopular atomic models was the "plum pudding" model. This model saidthat protons and electrons filled up all the space of the atomequally. We know now, and because of this experiment, that protonsare located at the very center of an atom and they take up verylittle space. If the plum pudding model were correct you wouldexpect the particles to all act the same; either all of them wouldbe reflected in the same direction or all of them would passthrough. But, if the protons were all tightly packed in the centeryou would expect most of the alpha particles to pass straightthrough the gold foil because they are just passing through emptyspace. Occasionally one might get close and be deflected a littlebit. Even more rarely you would expect to see some of the alphaparticles shoot right back at you. These are exactly the resultsyou see from the gold foil experiment and they show us that atomsare mostly empty space.
Because we know that the nucleus of an atom is very very small butthis is surrounded by a cloud of electrons. The distance betweenthe nucleus and the electron cloud is HUGE meaning that an atom is99.999999999999% empty space. When this space is taken away (as happens when a star collapsesinto a neutron star), something that was much bigger than the Sunbecomes a body barely larger than a city).
