A chemical symbol is the shortform of the name of an element. Usually, it is made up of one or two letters, but sometimes it is made up of three letters.

The chemical symbols of all elements are listed in the periodic table. They are also used while writing chemical equations.

For example: C + O2 → CO2

Here C stands for carbon and O stands for oxygen.

Some chemical symbols are the short forms of their English names. For example, H is the chemical symbol of hydrogen.

Some other chemical symbols are the short forms of their Latin names. For example, Na is the chemical symbol of sodium which is called 'Natrium' in Latin.

Other examples: Iron - Fe - Ferrous
