Vedclass · Answer

(C) The atomic number of Magnesium $(Mg)$ is $12$,which means it has $12$ protons $(p=12)$.The electronic configuration of a neutral $Mg$ atom is $2, 8, 2$.When $Mg$ forms a $Mg^{2+}$ ion,it loses $2$ electrons from its outermost shell,resulting in an electronic configuration of $2, 8$ (a total of $10$ electrons).Therefore,the $Mg^{2+}$ ion must have $p=12$ and $10$ electrons in its shells.Looking at the provided figures:- Figure $C$ shows $p=12$ and $10$ electrons (arranged as $2$ in the inner shell and $8$ in the outer shell).Thus,figure $C$ represents the $Mg^{2+}$ ion.

Identify the $Mg^{2+}$ ion from the figures,where $n$ and $p$ represent the number of neutrons and protons,respectively.
