Answer 1

Answer #1

(a)

Atomi radius increases from top to bottom in groups and decreses from left to right in periods.

Hence, the order of decreasing radius is as follows:

Sr < Ga < Al < Si < P < N

(b)

Metallic character increases from top to bottom in groups and decreses from left to right in periods

The order of decreasing metallic character is as follows:

Sr < Ga < Al < Si < P < N
