which of the following configurations represents atoms of the elements having the higest second ionisation energy?

A

`1s^(2)2s^(2)2p^(4)`

B

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

C

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

D

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

Text Solution

Verified by Experts

The correct Answer is:
C
Because for removing second electron, it has to be taken out from stable configuration that needs a large amount of energy.
