Strontium, Chemical Element
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
It's a radioactive beta emitter, produced by nuclear fission with a half-life of 29 years. Created by nuclear tests from 1945 to the early 1970s, strontium-90 made its way from the air to grassland, cow stomachs, dairy products and as 1950's studies showed into children's milk teeth. It collects in bones too, being of a similar size to its ...

Strontium: Source, Occurrence, Properties, and Detection
Strontium halides are formed from the interaction of strontium with halogens or by dissolving strontium hydroxide or carbonate in the corresponding hydrogen halide acid. Among halides, strontium fluoride, SrF 2, takes a special place because of its low solubility in water (nearly 0.12 g l −1) and diluted mineral acids.Strontium fluoride can be …

Strontium
Description. Strontium (Sr) is the 15th most abundant element in the earth's crust. Only two minerals, however—celestite and strontianite—contain strontium in sufficient quantities to make recovery practical, and these minerals are found predominantly in sedimentary rocks. Strontium is a silvery-yellow, metallic element.
