Is calcium oxide the same as calcium monoxide?

No, calcium oxide and calcium monoxide are not the same. Calcium oxide (CaO) is a compound formed from calcium and oxygen, where the calcium has a +2 oxidation state. In contrast, calcium monoxide (CaO) would suggest a +1 oxidation state for calcium, which is not a stable or common form. Therefore, calcium oxide is the correct term for the compound formed by calcium and oxygen.
