When a metal and a non-metal bond it forms an ionic compound. eg. Mg+O=MgO (Note. don't put an equals use an arrow instead)

(Magnesium and Oxygen make Magnesium Oxide

When two non-metals combine you can get one of two things; Covalent molecules or Giant covalent structures.

The molecules are usually found in naturally occurring gases eg. O2, N2, F2. these bonds are usually weak meaning low melting and boiling points.

Networks occur in either carbon or carbon+silicon. These are vast networks of atom all joined together meaning a high melting and boiling point (well into the thousands) and yields very strong materials such as diamonds.

When two or more atoms of the same element or a different element combine they form a compound.

ie. Hydrogen and Oxygen can combine and form a compound (hydrogen dioxide)

or two hydrogen atoms can combine and form a compound

It depends on what elements react as to what compounds they form. As examples a metal plus a halogen will give a salt. Carbon, hydrogen and oxygen will most likely give an organic compound. More than 60.106 compounds are known today. Two or more elements combined form a molecule.
