A

Ba

B

Mg

C

Ca

D

Be

Text Solution

Verified by Experts

The correct Answer is:
D
On moving down the group, ionization energy decreases. This is due to the fact that the electrons in lower shells experience higher force of attraction from the nucleus. Thus, it is difficult for them to ionise.
