History

Strontium was recognized as a new element in 1790 when Adair Crawford and his colleague William Cruickshank analyzed a mineral sample from a lead mine near Strontian, Scotland. The element was eventually isolated by Sir Humphry Davy in 1808. The isolation was done by the electrolysis of a mixture containing strontium chloride and mercuric oxide. Named after Strontian, a town in Scotland

Discoverers	A. Crawford
Discovery Location	Scotland
Discovery Year	1790
Etymology (Name Origin)	From the Scottish town, Strontian.
Pronunciation	STRON-she-em (English)

Strontium's non-radioactive isotopes are considered non-toxic

Strontium metal turns yellow when exposed to air

Uses

The primary use for strontium is in glass for color television cathode ray tubes. Strontium salts are used in flares and fireworks for a crimson color. Strontium chloride is used in toothpaste for sensitive teeth. Strontium oxide is used to improve the quality of pottery glazes. Used in flares and fireworks for crimson color. Strontium-90 is a long lived highly radioactive fallout product of atomic-bomb explosions.

Sources

Found in minerals celestite and strontianite.
