Used as a coating for steel cans since it is nontoxic and noncorrosive. Also in solder (33%Sn:67%Pb), bronze (20%Sn:80%Cu), and pewter. Stannous fluoride (SnF2), a compound of tin and fluorine is used in some toothpaste. Principally found in the ore cassiterite(SnO2) and stannine (Cu2FeSnS4). qEwCPJOP0Mg Tin

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 50 From the Anglo-Saxon word "tin" (the origin of the symbol Sn comes from the Latin word "stannum" meaning "tin")

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

Strontium metal turns yellow when exposed to air

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.
