The magnetic nature of atoms (or) ions of IIA elements is

A

Paramagnetic

B

Ferromagnetic

C

Diamaagnetic

D

None

Text Solution

Verified by Experts

The correct Answer is:
C
General electronic configuraation of IIA - group elements is `ns^(2)` and that of IIA group ions is `ns^(2)np^(6)`. So in both case they don’t have unpaired electrons so they are diamagnetic.
