The metal itself and oxygen. For example, in ferrous oxide or ferric oxide, there is iron and oxygen.
Metal oxide is the ionic bond combination of any metal element of the periodic table of elements with oxygen. The alkali metals and alkali earth metals are respectively the first and second columns of elements found on the periodic table. Thus, alkali metal oxides and earth metal oxides are types of metal oxides, but metal oxide does not imply alkali.
The elements found in ferrous oxide are iron (Fe) and oxygen (O).
elements and compounds
Calcium oxide (CaO) contain calcium and oxygen.
potassium and oxygen.
Smelting removes unwanted elements from metal.
Reaction between a metal oxide and a nonmetal oxide to produce a salt containing at least three elements is a synthesis reaction. The salt almost always contains at least one monatomic metal cation and at least one polyatomic anion that contains all of the elements of the reacted nonmetal oxide plus the oxygen atoms from the metal oxide. This type of anion is called an "oxyanion" or the "anion of an oxyacid."

metal and non-metal elements.
Aluminium Oxide is not a metal. Nor is it a non-metal. It is a compound formed from a metal [Aluminium] and a non-metal [Oxygen] The terms metal and non-metal are reserved for the elements that appear on the Periodic Table.
Non-metal oxide contains a non-metal chemically combined with oxygen.
Lead and oxygen are the elements in lead dioxide.
