Element Description

Chemically similar to calcium, strontium is softer and decomposes in water on contact. Strontium is silvery-white but, when exposed to air, it rapidly becomes yellow and forms an oxide film. In nature, it is found primarily as celestite (SrSO<sub>4</sub> and strontianite (SrCO<sub>3</sub>).
