What happens to the outer shell electrons of a calcium when it reacts with a oxygen atoms?

When calcium reacts with oxygen atoms, the outer shell electrons of calcium are transferred to oxygen atoms. This leads to the formation of calcium oxide (CaO) with calcium losing 2 electrons to form a Ca2+ ion and oxygen gaining 2 electrons to form an O2- ion.
