Is everything in the world acid,base or salt?

Dear Student 

In this world all things are made up of atoms and molecules. All things which are present in several forms such as either in the elemental form as the noble gases, in the acid and basic form, in the salt form like carbonate and oxide salt. Many are present in the allotropic form of atoms like coal. 

So, it is not necessary that every thing in this world are just made up of just acid, base and salt.
