Strontium is the chemical element with the symbol Sr and atomic number 38. An alkaline earth metal, strontium is a soft silver-white yellowish metallic element that is highly chemically reactive. The metal forms a dark oxide layer when it is exposed to air. Strontium has physical and chemical properties similar to … Zobacz więcej Strontium is a divalent silvery metal with a pale yellow tint whose properties are mostly intermediate between and similar to those of its group neighbors calcium and barium. It is softer than calcium and harder than barium. … Zobacz więcej Strontium commonly occurs in nature, being the 15th most abundant element on Earth (its heavier congener barium being the 14th), estimated to average approximately 360 parts per million in the Earth's crust and is found chiefly as the sulfate Zobacz więcej Consuming 75% of production, the primary use for strontium was in glass for colour television cathode-ray tubes, where it prevented X-ray emission. This application for strontium … Zobacz więcej Strontium-90 is a radioactive fission product produced by nuclear reactors used in nuclear power.
