Question

How would you explain how period and group trends in atomic radii are related to electron configuration?

Answer 1

Atomic size gradually decreases from left to right across a period of elements. This is because, within a period or family of elements, all electrons are added to the same shell. ... Down a group, atomic radius increases. The valence electrons occupy higher levels due to the increasing quantum number
