Magnesium is in the second group in the periodic table, which means that its outer shell is an s-orbital which contains 2 valence electrons.
Hydrogen also has an s-orbital as an outer shell but it only contains 1 valence electron. The electron dot diagram would look like this:
H· ·Mg· ·H
Each hydrogen shares one electron with magnesium and the magnesium shares one of its electrons with each hydrogen resulting in two covalent bonds.
H:Mg:H and this gives us the compounds MgH₂
