We usually divide properties into .

If we want to list the chemical properties of sodium, for example, we must state how it reacts with water and chlorine. Then comes hydrochloric acid, molten carbon, etc. Every property is a separate chemical property. We might list thousands of chemical properties.

If we want to list all the physical properties of sodium, we must state its colour and physical state. Then come melting point, boiling point, and thermal and electrical conductivities. We must include , critical point, and heats of fusion and vaporization. We might list dozens more of physical properties.

A substance can have any number of properties.
