In chemical equations if Oxygen or Chlorine is one of the reactants they are represented as ' $O_{2}$ ' and ' ${C l}_{2}$ ' but not as ' $O$ ' or ' $C l$ '. Why?

Solution

Oxygen and chlorine exist as gases as their natural states. And both chlorine and oxygen are diatomic gases in the stable states. So, they are usually represented as $O_{2}$ & $C l_{2}$
