Molecular formula :
MW :
CAS :

nature : Periodic System II of the main ethnic group elements (alkaline earth metals). Atomic number 38. Stable isotopes : 84,86,87,88. Amu 87.62. The silver-white metal. If the soft wax. Density 2.6. Boiling Point 1384 ° C The temperature of 769 ° C. Valence +2. Chemical properties and lively. In the air when burning heating. Easy with water and an acid (strong reaction Mn) and release hydrogen. Volatile salt in its colorless flames were bright red. For chemical analysis, the fireworks, light flares, such as photocell. Strontium 90 is a radioisotope and can be used for beta-ray sources. Treatable breasts. The half-life of 25 years. The major minerals are lapis lazuli and strontium carbonate ore. Strontium can be electrolytic metal melting and the strontium chloride obtained.
