Because of this need, humans and animals have a built-in taste for salt. All salt contains two basic elements: sodium and chlorine. Sodium (chemical symbol Na) is a silvery-white metal that reacts violently when mixed with water and oxidizes in air. Chlorine (chemical symbol Cl) is greenish-yellow and exists as a gas at room temperature.
