STRONTIUM. Strontium was discovered by Adair Crawford (GB) in 1789. Named after the village of Strontian in Scotland. It is a soft, malleable, silvery-yellow metal that is combustible in air and reacts with water. Exposed surfaces form protective oxide film. It ignites and burns readily. Strontium is found in minerals celestite and strontianite.
Strontium-90, a radioactive isotope of strontium, is a common product of nuclear explosions. It has a half-life of about 28.8 years and decays into yttrium -90 through beta decay . Strontium-90 is especially deadly since it has a relatively long half-life, is strongly radioactive and is absorbed by the body, where it accumulates in the skeletal ...

Strontium is a member of the alkaline earth metals. The alkaline earth metals make up Group 2 (IIA) of the periodic table. The periodic table is a chart that shows how chemical elements are related to one another. Other alkaline metals include beryllium, magnesium, calcium, barium, and radium. Strontium occupies a middle position in the family.
Strontium-90, a radioactive isotope, is a by-product of nuclear reactors and present in nuclear fallout. It has a half-life of 28 years. It is absorbed by bone tissue instead of calcium and can destroy bone marrow and cause cancer. However, it is also useful as it is one of the best high-energy beta-emitters known.
Reaction of strontium with sulfate. Sr (II) is precipitated by sulfate ions at neutral or slightly acidic solutions. The sulfate is a white crystalline precipitate. Sr 2+ (aq) + SO 42− (aq) SrSO 4 (s) In strong acidic solutions SrSO 4 dissolves as the sulfate concentration becomes to small: SO 42− (aq) + H + (aq) HSO 4− (aq), L [SrSO 4 ...
While natural strontium is harmless, one of its isotopes, Sr-90, carries a more sinister reputation: It is a dangerous byproduct of nuclear fallout. Highly reactive. Strontium is quite common in nature — it is the 15th most abundant element in Earth's crust, according to the Minerals Education Coalition (MEC).

Strontium (Sr) is a silver metal with a yellowish tint named for the Scottish village of Strontian, where the mineral strontianite was discovered in 1790. Its properties closely resemble and are intermediate between those of calcium and barium. Strontium will oxides a darker …
Real strontium. Strontium metal is hard to get. In fact, it was in the very last group of elements I was able to acquire to complete my collection. It was donated by the extremely kind Max Whitby of the The Red Green & Blue Company, which sells a complete collection of elements. They sell a very nice element collection in several versions.
