The phrase "Chemical property" is context driven, but generally refers to the material's behaviour at standard conditions (i.e. room temperature, 1 atmosphere pressure, oxygen bearing atmosphere). This property becomes apparent during a chemical reaction.

A usefully general term, it is used to encompass, amongst other things:

• the phase of matter; solid, liquid or gas
• the material's reactivity towards other materials
• preferred oxidation state(s)
• molecular shape and bond orientation
• bond length
• coordination number
• preferred types of bonds to form eg metallic, ionic, covalent
