Answer 2

Answer:

hey mate!!

Here is ur ans

Explanation:

a) Nitrogen have bid atomic radii than lithium.

-> Because Nitrogen have Many atoms than lithium

b) Potassium have +1 charge and chlorine have -2 charge

-> Because potassium donate 1 electrons that's why potassium have +2 charge and Nitrogen receive 2 electron from potassium that't why nitrogen have -2 charge

c) magnesium have 2 valency and calcium have also 2 valency

-> In the last shell of both electron their was 2 electrons are present so that magnesium and calcium have 2 valency
