what happens to the atomic size
Asked by | 27 Feb, 2008, 06:36: PM
Expert Answer

Moving from top to bottom the atomic size increases as the electron is added in a new shell and the inner shell show screening of the nucleus and the outer electrons and the nuclear pull becomes weak. On moving from left to right in the periodic table the size decreases as the electron is added in the same shell and nulceus pulls the outer electrons strongly and as the nuclear pull becomes stronger the size decreases.
