Concept introduction:

Chemical compounds are made up of more than two atoms with definite proposition. Chemical formula can express by single line formula contains chemical symbols of each element of atom, numbers in subscript that tells number of atoms in the compound. Sometimes chemical formula contains dashes, comma, plus and minus signs.  On naming chemical compound, common names are mostly used instead of systematic name. Because of before chemical formula determination common name were already used.

Sometimes chemical compounds have common name as well as systematic name.  Example, ${\text{H}}_{\text{2}}\text{O}$ is water and it has systematic name is dihydrogen monoxide.  Systematic name that identify the ratio of the element present in the compound.  Systematic name is much difficult but it has advantage that chemical formula of the compound can be identified by the name
