What is a chemical propery?

(combustibility)

A chemical property is any characteristic that gives a substance the ability to undergo a change that results in a new substance.

Example: Matches are permanently changed and black after they are burned. Therefore this property can be observed only by changing the composition of the match. Or for instance when you bake pie you put the ingredients in but never can take them out!

The chemical property of a given element refers to the property that is used to characterize the reaction of the materials hence their identity.
