CHEMICAL PROPERTIES- A characteristic of a substance that describes its ability to change into different substances. Flammability (how easy to burn), freezing, oxidizing, combustion (amount of energy released when burnt), toxicity (how much damage and how quickly a substance affects an organism), radioactivity.
