True or False: The elements in a compound keep their

properties?

False. They undergo a chemical change, meaning their matter changes and they do not keep their properties. Sodium Chloride (salt) is formed by the elements sodium (which reacts violently with water) and chlorine (poisonous gas). When they undergo a chemical change together they create a harmless substance that is safe to eat.
