What are compounds?

Q5. What are compounds?

Ans.  They are substances made from two or more elements joined together. Every molecule in a compound is the same combination of atoms. Sodium chloride, for instance, is one atom of sodium joined to one of chlorine. Compounds have different properties to the elements that make them up. Sodium, for instance, spits when put in water; chlorine is a thick green gas. Yet sodium chloride is ordinary table salt.
