Strontium is a soft silver-white or yellowish metallic element that is highly reactive chemically. The metal turns yellow when it is exposed to air and has physical and chemical properties similar to those of its two neighbours, calcium and barium. It occurs naturally in the minerals celestine, putnisite and strontianite.
