The formula for calcium oxide is CaO.
This compound is ionic which means that a positively charged ion, a cation, has an electrostatic attraction to oxygen, which is negatively charged, an anion.
Since calcium has a plus 2 charge and oxygen has a negative 2 charge, there is one ionic bond holding these atoms together in an ionic bond.
