Question

14. Arrange each pair of ions in order of increasing ionic
radius
(a) Mg2+ and Al3+ (b) 02- and S2- (c) 02- and F-​

Answer 1

Explanation:

a) Atomic radii of both mg 2+and Al3± is same because in both case it has 10 electron sin it give extra electtron

b)S2- has greater atomic radii since it has 3 shell

but O2- has smaller Atomic radii because it hass 2 shell

c) in both ion have same atomic raddii because it has same shell and eight electron in valence cell

Answer 2

Explanation:
