What a good question. Covalent bonding is a form of chemical bonding that is characterized by the sharing of pairs of electrons between atoms. In order to do this the electrons have to be of a similar energy and when the bond is formed it has to be of lower energy than the starting position. The most common covalent bonds are, as you say, between non-metals. There are also covalent bonds between some metals and non-metals. Covalent bonds between metals are rare one example is between molybdenum atoms, but this is very unusual.
Does this help?
why does only covalent bond form between two or more nonmetals but not metals?...i am a eighth grader so i am not sure if i need to know them.
