First, second & third ionization energies are 737, 1045 & 7733 `KJ//mol` respectively. The element can be `:`

A

`Na`

B

B

C

Al

D

Mg

Text Solution

Verified by Experts

The correct Answer is:
4
Mg has two electrons in tis `s-` subshell after removing these electrons it will obtain inert gas configuration . So a big jump in `I.E.` will be there.
