• Na ( Sodium ) has atomic number 11 and hence 11 electrons.

[Cation :- ions with positive charge ( atoms which donate one electron gains one positive charge ) ]

[ anion :- ions with negative charge ]

Mg^(+1) after loosing one electron gains +1 charge

Al^(+2) after loosing two electrons gains +2 charge .
