A molecule is formed when atoms join together by chemical bonds. There are over a hundred different types of atom, called elements. The atoms of a particular element are identical to each other.
An element is a substance that can't be broken down into another substance. Elements are composed of only one type of atom. For example gold is made up of only gold atoms. Comâ¦pounds are substances made up of more than two elements. For example water(H2O) is made up of the elements hydrogen and oxygen. Compounds can be broken down into simpler substances.
