Which element having the following electronic configuration has minimum ionisation potential?

A

`1s^(1)`

B

`1s^(2),2s^(2),2p^(6)`

C

1s^(2),2s^(2),2p^(6),3s^(1)`

D

`1s^(2),2s^(2)2p^(2)`

Text Solution

Verified by Experts

The correct Answer is:
C
`1s^(2)2s^(2)2p^(6)3s^(1)`. It belongs to IA group which has least ionisation potential and it decreases down the group.
