What is the ionic formula for calcium oxide? | Socratic

The ionic formula for calcium oxide is simply CaO. Why is this the case? The Calcium ion is an Alkaline earth metal and wants to give up the 2 s orbital elections and become a +2 ion. Oxygen has six valence electrons and is looking to gain two electrons to complete the octet (8) electron count in the valence shell making it a -2 anion. When the charges of the Calcium +2 and the Oxygen -2

Calcium - Wikipedia

2019-4-16 · Calcium is a chemical element with syol Ca and atomic nuer 20. As an alkaline earth metal, calcium is a reactive metal that forms a dark oxide-nitride layer when exposed to air.Its physical and chemical properties are most similar to its heavier homologues strontium and barium.It is the fifth most abundant element in Earth''s crust and the third most abundant metal, after iron and aluminium.
