The correct statement among the following is:

Options

A. the first ionization energy of `AI` is less than first ionizarion energy of `Mg`.
B. the second ionization energy of `Mg` is greater than second ionization energy of `Na`
C. the first ionization energy of `Na` is less than first ionization energy of `Mg`.
D. the third ionization energy of `Mg` is greater than third ionization energy of `AI`.

Answer

B

Explanation

`IE_(2)` of `Na gt Mg` as in `Na`, second electron is to be removed from stable inert gas configuration i.e. `1s^(2)2s^(2)2p^(6)`.
