Chemical Formula and Equations - The Periodic Table

Chemical symbols (Element symbols) from the periodic table are used for the individual elements e.g. H for hydrogen, C for carbon, O for oxygen, N for nitrogen, Ca for calcium and Na for Sodium. Substances that have two or more atoms bonded together, and therefore more than one element e.g. H 2 O are called compounds.
