Na, an alkali metal, is very reactive because it only needs to lose one electron to have a full octet. Therefore, the Na2O bond is the strongest because the Na atom is the most likely to lose an electron to the O atom.

Ahhhhhh okay that makes sense...I should have thought of that...I thought maybe it had something to do with electronegativity  thanks :D!!!
