Answer

Brief Explanations:

Water ($H_2O$) is a compound, silver (Ag) is an element, carbon - dioxide ($CO_2$) is a compound, and oxygen gas ($O_2$) is an element. All of them are made of matter and contain atoms. Compounds are made of different types of elements, and elements are made of the same type of atoms.

Answer:

They are each made of matter. Some are compounds and some are elements. They all contain atoms.
