Elements‚ Mixtures and Compounds An element is a pure substance made of one type of particle (atom). Particles can join up with other particles of the same type to form molecules. Examples: Hydrogen = H2 . This means there are two atoms of hydrogen joined together to form a molecule of hydrogen gas. Oxygen = O2‚ Nitrogen is H2‚ Chlorine is Cl2. A compound is a pure substance of two or more elements chemically combined together in a set ratio. Example: Water = H20 this means there are always
