Which of the following relation is correct with respect first (I) and second (II) ionisation of sodius and magnesium?

A

`I_(Mg)=II_(Na)`

B

`I_(Na) gt I_(Mg)`

C

`II_(Mg) gt II_(Na)`

D

`II_(Na) gt II_(Mg)`

Text Solution

Verified by Experts

The correct Answer is:
4
Second ionisation energy of sodium is greater than that of Mg. In case of sodium ion`(i.e. Na^(+))` the electron the electron removal from the stable inert gas configuration `(1s^(2)2s^(2)2p^(6))` requries much higher energy.
