Since your teeth are also bones, it helps to decrease your risk of cavities as well! A radioactive form of strontium, available in dietary supplements, treats cancer due to its ability to destroy cancer cells. That is why it is used to treat osteoporosis. Strontium increases your bone mineral density and reduces the risk of bone fractures. The most common of these is in the treatment of osteoporosis and tooth decay. The element strontium is used in multiple types of medicines. This is also due to its reactivity with the air at room temperature. As previously mentioned, these red salts produce flare guns and red fireworks. Strontium aluminate (and it illuminates!) has the phosphorescent quality that slowly allows it to re-emit light over a certain period of time. These plastics are “rechargeable” by exposing them to sunlight or to a bright flashlight. Glow-in-the-dark plastics utilized the element strontium. The use of strontium carbonate in the cathode ray tubes prevents this! However, as the modern day transitions towards more flat-panel technology, television manufacturers no longer need strontium. One of the main concerns in the creation of televisions was exposing people to X-ray emissions. Strontium in Today’s World Strontium’s Uses in EntertaimentĬhances are that you see strontium active in the world around you every day! Strontium carbonate is used in the making of glass for cathode ray tubes (CRT). Additionally, the element has an electronegativity of 0.95 on the Pauling scale. It has an electron configuration of 5s 2. The fourth element in the alkaline earth metals on the periodic table is strontium. It is located in the s-block of the periodic table, below calcium and above barium. Strontium has the atomic symbol Sr with an atomic number of 38. Refining in glazing often uses compounds containing strontium.The isotope strontium-90 is a component of nuclear fallout.Due to strontium’s reactivity with the air and water, it is only naturally found in minerals.The element strontium is the 15th most abundant element in the Earth’s crust.Strontium turns yellow when exposed to air.Strontium derives its name from the town it was originally mined from in Scotland, Strontian.China is the top-producer of strontium with roughly 2/3 of the world’s production.Strontium is used in cancer therapy due to its characteristic of being the best high-energy beta emitter with the longest lifespan.It’s used in certain toothpastes to aid sensitive teeth.The most accurate atomic clock (to one second in the 200 million years) uses strontium atoms.It’s most commonly known for its uses in flares and red fireworks, but it also used in glow-in-the-dark plastics, in color television, and in modern medicine. Strontium is a silvery-yellow, soft metal element.
