Here is a list of atomic numbers and atomic weights. The radius of an atom can be estimated by taking half the distance between the nucleus of two of the same atoms. For example, the distance between the nuclei of is 2.66 Å, half that distance would be the radius of atomic iodine or 1.33 Å. Using this method the atomic radius of nearly all the elements can be estimated. Note that going across the periodic table, the atomic radius decreases. This is due to the fact that the principal energy…
