Some molecules consist of two atoms of the same element. For example, O 2 is the oxygen molecule most commonly found in the earth's atmosphere; it has two atoms of oxygen. However, under certain circumstances, oxygen atoms bond into triplets (O 3), forming a molecule known as ozone.
A formula tells what elements make up a molecule. For example, a molecule of water is made up of two hydrogen atoms and one oxygen atom. The formula for a molecule of water is H2O. Molecules come in different sizes and molecular weights.
