The addition of two more electrons to make Ne2 fills all the bonding and antibonding MOs. Therefore, the bond order of Ne2 is zero, and the molecule is not expected to exist.
78 electrons
There are 10 electrons in an Mg2+ ion.
51
Calcium normally has 20 electrons. Because it has a plus 2 charge, it must have two less electrons. Therefore, the calcium ion has 18 electrons.
