What is atomic size?
Atomic size is the distance between a nucleus of an atom and it's valence or outermost shell .
Atomic size is a very important characteristic of an atom to understand the reactivity .
On this property all other properties can be figure out .
Does it increase or decrease down the group.
From right to left across a period, metallic character increasesbecause the attraction between valence electron and the nucleus isweaker, enabling an easier loss of electrons. Metallic characterincreases as you move down a group because the atomic size is increasing.
