Order of first ionisation potentials of elements `Li,Be,B, Na` is

A

`LigtBegtBgtNa`

B

`BegtBgtLigtNa`

C

`NagtLigtBgtBe`

D

`BegtLigtBgtNa`

Text Solution

Verified by Experts

The correct Answer is:
B
Ionisation potential increases as we go from left to right in a period. While it decreases as we come down a group.
`{:(Be,B,Li,Na),(9.3,8.3,5.4,5.1):}`.
