Question

radius of an atoms are follows:- y (2,1) and x(2,8,8,1) Justify y < x radius

Answer 1

Atom y has (2,1) & where atom X has (2,8,8,1).This means that atom X has more number octets. So the distance from the nucleus to the last octet more than that of atom y. Hence, atom X has bigger atomic radius.
