Links at the bottom. This elements major industrial use is for glass for a color television on the cathode ray tube. It prevents x-rays from coming out of your tv. It could also be used in toothpaste if its combined with chloride. 99% of strontium in the body is in the bones. Strontium could be taken as a supplement through the mouth to cure osteoporosis. Strontium Chloride is used as a medicine to stop pain and build strong bones. It is found and toothpaste to cure sensitive teeth. The cost of 1kg of strontium is 1000$. The abundance of this element on earth is 0.036%. The abundance of Strontium in the universe is 4.x10-6%. Strontium is found in the solid phase when its at its normal state in nature. Strontium is a alkaline earth metal. Strontium Boiling point:1050 K (777 °C, 1431 °F). Melting point:1650 K (1377 °C, 2511 °F). Density-2.64 g·cm−3(at 0 °C, 101.325 kPa). Strontium is a good conductor. Strontium can be radioactive and has a beta decay. When it decays it has a half life of 28.79 years.
It was discovered in 1787 by William Cruickshank but it was synthesized and isolized in 1808 by Humphry Davy. It was discovered in a scottish village of Strontian in a mine.
