Atomic radius is the measure from the middle of an atom to the outter edge. Usually mesured between two atom. Measure from the middle of one atom to the middle of another and then divide by two.
it is the distance from the center of the nucleus to the outerportion of the electron cloud. The radius of an isolated, neutral atom will range between 30 and300 trillionths of a meter, or between 0.3 and 3 Ã¥ngstrÃ¶ms .
When looking at a periodic table, atomic radius increases from top to bottom, and decreases from left to right. The bottom left corner is the largest, while the top right corner is the smallest radius.
Depends entirely on its yield. Some hydrogen bombs had yields less than 1MT, some more. Otherscould provide a wide range of yields, all in one bomb. The userjust needed to select the best yield for the particularapplication. So a 1MT bomb would have a blast radius of several 10s of miles, a50MT bom…b would have a blast radius of 100's of miles. Thecurvature of the Earth can help protect from heat and radiation,but the blast wave can reach beyond the horizon due to atmosphericfocusing. (MORE)
The relationship between atomic number atomic radius in inverselyproportional. The atomic number will increase as the atomic radiusdecreases.
The single proton that forms the nucleus of the hydrogen atom has a radius of approximately 1.0x10-12.The hydrogen atom itself has a radius of approximately 52.9 What fraction of the space within the?
The units for this question are 1.0x10-13 cm and the radius of theatom is 52.9 pm (pico meters) (the nucleus is -13 not -12).
Helium usually is listed with the smallest atomic radius when calculated. Hydrogen however has a smaller van der Waals radius
Hydrogen and carbon do not create a new compound by themselves. Tocreate a new compound, they would need to bond with atoms of moreelements.
The calculated atomic radius of chromium is 166 pm; for more details see the link below.
The calculated atomic radius of beryllium is 112 pm (1 pm = 10 -12 m).
When an electron absorbs a photon and therefore has more energy, it will move to a higher orbital and the radius of the atom will increase. This is generally a temporary state of affairs, since the electron will eventually re-emit the photon and fall back to its ground state.
The molecular formula for Hydrogen peroxide is H 2 O 2 . It has 2 hydrogen and 2 oxygen. Another way of writing it is H-O-O-H.
the further right you go on the periodic table, the atomic radius decreases. the further down you go on the periodic table, the atomic radius increases. you can determine where an atom is generally placed on the periodic table based on its atomic radius.
\nA hydrogen atom is one proton with an electron orbiting it. Said hydrogen atom will not remain a hydrogen atom for long--it wants nothing more than to bond to another atom, and isn't really all that fussy about what it bonds to. It will bond to, among other things, an oxygen atom to make water, a …chlorine atom to make hydrochloric acid, a fluorine atom to make hydrofluoric acid--VERY dangerous stuff!--carbon atoms to make hydrocarbons, carbon and oxygen atoms to make carbohydrates...It also likes to bond to iron, which makes weak iron products.

you measure the distance between the nuclei of 2 touching atoms then taking that distance and cutting it in half
Atomic radius, is called the width of an atom, but it is not a precisely defined physical quantity, nor is it constant in all circumstances. The value assigned to the radius of a particular atom always depends on the definition chosen for "atomic radius," and the appropriate definition depends on th…e context.. The term "atomic radius" itself is problematic: it may be restricted to the size of free atoms, or it may be used as a general term for the different measures of the size of atoms, both bound in molecules and free. In the latter case it should also include ionic radius, as the distinction between covalent and ionic bonding is itself somewhat arbitrary.. The atomic radius is determined entirely by the electrons: The size of the atomic nucleus is measured in femtometres, 10,000 times smaller than the cloud of electrons. Electrons, however, do not have definite positions-although they are more likely to be in certain regions than others-and the electron cloud does not have sharp edges.. Despite (or maybe because of) these difficulties, many different attempts have been made to quantify the size of atoms (and ions), based both on experimental measurements and calculation methods. It is undeniable that atoms do behave as if they were spheres with a radius of 30-300 pm, that atomic size varies in a predictable and explicable manner across the periodic table and that this variation has important consequences for the chemistry of the elements. Atomic radii decreases from Alkali Earth metals to the Noble Gases on the far right side of the periodic table. This is determined by the effective nuclear charge that increases with added electrons in a period. The atomic radii increases as you go down each column with added electrons in a period. (MORE)
Helium usually is listed with the smallest atomic radius when calculated. Hydrogen however has a smaller van der Waals radius The protium isotope of hydrogen has the smallest nucleus radius. It is 1.6 fm
A molecule consists of many atoms. When you have a hydrogen molecule, or whatever other type of molecule for that matter, you have many hydrogen atoms that make it.
in the same period, as the atomic number increases, the atomic radius decreases. in the same group, as the atomic number increases, the atomic radius increases.
When the valence level fills up, a new level is made a bit further from the nucleus. This trend on the periodic table increases as you go down the groups.
The atomic radius of a chemical element is a measure of the size of its atoms, usually the mean or typical distance from the nucleus to the boundary of the surrounding cloud of electrons . Since the boundary is not a well-defined physical entity, there are various non-equivalent definitions …of atomic radius. Depending on the definition, the term may apply only to isolated atoms, or also to atoms in condensed matter , covalently bound in molecules , or in ionized and excited states ; and its value may be obtained through experimental measurements, or computed from theoretical models. Under some definitions, the value of the radius may depend on the atom's state and context.  The concept is difficult to define because the electrons do not have definite orbits, or sharply defined ranges. Rather, their positions must be described as probability distributions that taper off gradually as one moves away from the nucleus, without a sharp cutoff. Moreover, in condensed matter and molecules, the electron clouds of the atoms usually overlap to some extent, and some of the electrons may roam over a large region encompassing two or more atoms. Despite these conceptual difficulties, under most definitions the radii of isolated neutral atoms range between 30 and 300 pm ( trillionths of a meter), or between 0.3 and 3 angstroms . Therefore, the radius of an atom is more than 10,000 times the radius of its nucleus (1-10 fm ),  and less than 1/1000 of the wavelength of visible light (400-700 nm ).. The approximate shape of a molecule of ethanol , CH 3 CH 2 OH. Each atom is modeled by a sphere with the element's Van der Waals radius .. For many purposes, atoms can be modeled as spheres. This is only a crude approximation, but it can provide quantitative explanations and predictions for many phenomena, such as the density of liquids and solids, the diffusion of fluids through molecular sieves , the arrangement of atoms and ions in crystals , and the size and shape of molecules . [ citation needed ] Atomic radii vary in a predictable and explicable manner across the periodic table . For instance, the radii generally decrease along each period (row) of the table, from the alkali metals to the noble gases ; and increase down each group (column). The radius increases sharply between the noble gas at the end of each period and the alkali metal at the beginning of the next period. These trends of the atomic radii (and of various other chemical and physical properties of the elements) can be explained by the electron shell theory of the atom; they provided important evidence for the development and confirmation of quantum theory . re...

Atomic center is the center of the atom, also called as Nucleus. Atomic Radius is the distance between the center of the nucleus and outermost shell of the atom. It is nearly about 1.2 * 10 -10 m.
No it may not. There are specific orbits that electrons can use. They are related to the energy it takes to move an electron to an upper orbit.
The radius of nucleus of an atom is of the order of 10 -15 m.
133 what? what are the units here? err.....i suppose its tht of Fluorine's......hey, if u find out if flourine's atomic radius is more thn tht of helium's, jus lemme know. thnq
Rubidium; the next higher atomic numbered element in the same column of the periodic table always has a higher atomic radius, with some exceptions among transition elements due to the "lanthanide contraction". However, potassium and rubidium are not transition elements.
atoms are the building blocks of all matter, a molecule will contain atoms within it
Ionic radius is greater than atomic radius in a negative ion and less than it in a positive ion.
The covalent atomic radius of argon is 106 +/- 1o pm (pm is the acronym of the picometer).
As we move left to right across a period of a periodic table ,atomic radius decreases due to increase in effective nuclear charge and if we move top to bottom across a group then atomic radius increases due to decrease in effective nuclear charge.
Nuclear radius increases as you go down and to the left on the periodic table due to effective nuclear charge. Bassicaly, it means that sheilding of electrons by larger atoms having more things in the way that blocks the ability of the nucleus to pull on the electrons, thus the electrons are able to… be further from the nucleus and have a larger radius.

Be because as you move across the periodic table from left to right it decreases and as you go from top to bottom it increases.
Iodine has 53 electrons in its orbitals while fluorine only has nine. This does not even count the proton/neutron variance.

No, the charge either pulls the electron cloud closer (cation) or pushes it away (anion).
Firstly, atom made up of nucleus and electrons. More atoms join up to make a molecule. Hydrogen is made up of bunch of molecules form by 2 Hydrogen atom join together.

(i) By thermal dissociation When molecular hydrogen is heated at 5000C,it dissociates into atomic hydrogen.. (ii) By electric discharge At o.1 mm Hg to 1.00 mm Hg pressure.
3 i think no one, hydrogen is the lightest element on the periodic table it is also very flamable ever heard of the dirigible that contained hydrogen and blew up? killed many people so now everyone uses helium...
no atomic radius is not the same as atomic mass because it is 10 to the power of 10 and atomic mass is different for different elements
The trend for atomic radius, and most other trends on the periodic table, can be explained by the amount of attraction between the positively charged nucleus and the negatively charged electrons. Other factors that come into play are the number of electrons in the outer energy level (valence shell) …and the distance between the outer electrons and the nucleus (number of energy levels.) (MORE)
Two atoms of same element (for a given isotope) are identical and hence have the same atomic radius..
A molecule of hydrogen is two atoms of hydrogen bonded together sothat they share their single electrons, making them act as if theyhad a full s1 orbital in both atoms.
The atomic radius, is the measured size of the atoms of a chemical element.Usually this is the typical distance between the nucleus and the boundary of the surrounding electrons.
Trick question. The answer is vastly simplified--perhaps to thepoint of inaccuracy. Having worked on a system that carried either payload, I can tellyou that a hydrogen device will produce a larger blast radius withless long term radiation than the same physically sized uranium orplutonium device, …but that efficient detonation does not occuruntil above the 50 kiloton range--not much of an issue when theaverage size of the devices of the five NPT states is taken intoaccount. Much of the radiation released by a hydrogen reaction isin the form of heat, hence the term thermo -nuclear. Allhydrogen bombs are fusion bombs. Solely uranium and plutonium bombsare fission devices. The difference is in the reaction (fissionsplits the atom, fusion compresses two hydrogen atoms into a heliumatom--similar to the mechanism of stars). Additionally, allhydrogen bombs also have a fissile component that is used tocompress and initiate the fusion reaction. (MORE)
Oh, yes it is. because hydrogen has only one electron in its orbit and a smallest elemental atom too.
The diameter of an atom varies between 62 and 520 pm, depending on on the specific type of atom.
The radius of the nucleus is much smaller and also stays the same size for every ion of the same element. The radius of the atom is significantly larger, and its size changes depending on which ion of the element it is.
Al has 3 electron shells. Be has 2 electron shells. So Al has a larger atomic radius.
The atomic radius is the distance from the nucleus of an atom to the outermost orbital of electron.
