  • When two or more atoms are bonded together, they are known as a molecule. Ice, water and steam. The bottom rows shows the differences in their H2O molecules Ice, water and steam are all made up of H2O molecules.

  • Many solids, liquids and gases are made up of molecules! A molecule of oxygen (O2) Oxygen gas is made up of many oxygen molecules (each molecule is two oxygen atoms bonded together)
