It occurs combined with other chemicals, such as sulfur, carbon or oxygen. It is very light and its density is half that of iron. Barium oxidizes in air, reacts vigorously with water to form the hydroxide, liberating hydrogen. Barium reacts with almost all the non-metals, forming often poisoning compounds. language code: en);
