Magnesium and calcium are both in the second column of the periodic table, so they have 2 valence electrons or two electons in their outer shell. Valence electrons determine how chemicals react, so both of these are likely to give their two valence electrons away during the formation of an ionic bond-- leaving them with a +2 charge. They are both metals.

They are both metals (even though when we think of calcium, we think of milk).
