Jazlyn Solis · Answer 1

The formula of calcium and oxygen is CaO.

The reason why this is the equation is because Calcium is a + 2 cation. Oxygen is - 2. When they are equal, it's like opposite attract; which equals CaO.

Joyce · Answer 2

The ionic formula for calcium oxide is simply CaO. The Calcium ion is an Alkaline earth metal and wants to give up the 2 s orbital elections and become a + 2 cation. 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.
