Under normal condition which of the following electronic configuration is able to form dipositive ion

Options

A. `[Ar]4s^(1)`
B. `[Ne]2s^(2)3p^(6)`
C. `[Ne]3s^(2)`
D. None of these

Mg has only two electrons in the 3s-orbital and hence its I.E. is lowest, i.e. It has the maximum tendency to form dipositive ions.
