Answer:  Atoms want to be like a "noble gas" with a filled outer shell. I think it has to do with being in a stable state. For Mg, it's a lot easier to drop 2 electons to look like Ne rather than gain 6 to look like Argon.

As the atomic no. of magnesim=12

therefore ,by electric configuration we get

=2,8,2

As the no. of atoms is less than 5 it is easy to lose from gaining as it took some more difficulties!!!

hope its help!!✌✌✌✌✌
