Billions and billions of copper atoms stack together to form a piece of copper. Each mineral has a fixed chemical composition. Some minerals are made up of just one chemical element-they contain only one type of atom.Native copper is made up of copper atoms only.Most minerals are chemical compounds-they contain atoms of more than one chemical element.ach mineral is defined by its particular chemical composition and crystal structure. To explain what a mineral is properly, we have to introduce you to a bit of chemistry. Minerals are made up of chemical elements. A chemical element is a substance that is made up of only one kind of atom.
