Are all atoms the same size?

Answer 1

Nope. Each atoms beloning to one element are considered to be the same size. However atoms belonging to different elements have different sizes. Those sizes are measured by the atomic radius (in Angstroms).

Answer 2

The size of an atom depends mostly on the number of electrons. Atoms are the same size unless they gain or lose electrons which would affect the size of the electron cloud.If the atom is an isotope, then the size is different, but if it's a neutral atom, then it's the same.

Answer 3

Almost. As you go up the atomic table the number of occupied electron orbits increase as the the lower ones fill up, but the radius of the orbits decrease because of the increase of the nuclear charge. When the first electron is added to an nth Bohr orbit , it sees an effective charge of 1, that is Z of the nucleus minus the effect of the Z-1 electrons already in place, so it will have about the same size as an hydrogen atom. The largesr atom is Cesium. See http://antoine.frostburg.edu/chem/senese/101/periodic/faq/what-atom-is-largest.shtml

Answer 4

No, not all atoms are the same size. Electrons are basically 3 atoms stuck together but are still considered an atom. Then there's your ordinary atom! Now, what do you think? Which is bigger, 3 atoms or 1 atom?

Answer 5

No. Think logically, if all atoms were the same size than there wouldn't be any differentiation of elements. There are 92 natural elements on earth, all of the elements vary in size and weight/mass. An atom may seem very minute, but there is defantely a difference.

Answer 6

almost... by human standards :)
