Strontium Research Paper

The element that I choose for this project is called Strontium. Strontium is a chemical element with the symbol (Sr) and it has atomic number of 38. It is an alkaline earth metal, and is a soft white yellowish metallic element which has highly reactivity chemically. It’s properties are mostly intermediate between aand similar to those of its group neighbors calcium and barium. When it is exposed to air, the metal forms a dark oxide layer. Strontium has 38 protons, 50 neutrons, and 38 electrons. The electron configuration of Strontium is 1s^(2) 2s^(2) 2p^(6) 3s^(2) 3p^(6) 3d^(10) 4s^(2) 4p^(6) 5s^(2) or [Kr] 5s^(2). Strontium has an mass number of 87. Strontium can be a naturally element that can be found in rocks, soil, dust, coal, and oil. It best known for the brilliant reds that its salts give to fireworks and flares. It used for producing ferrite magnets and refining zinc. It can be also used for the production or manufacture of color television picture tubes. Strontium chloride hexahydrate is an ingredient in a toothpaste for sensitive teeth. Strontium was discovered in 1790 by Adair Crawford, an Irish chemist. Strontium is named after Strontian, a village in Scotland. It was identified as an element the next year after testing its crimson-red flame color. The melting point is 1050 K(777 °C, 1431 °F) and the boiling point is 1650 K(1377 C, 2511 F). https://en.wikipedia.org/wiki/Strontium …show more content…
Strontium hydroxide is a strong base even though it is not strong as the hydroxides of barium. Natural strontium is a mixture of four stable isotopes. https://en.wikipedia.org/wiki/Strontium Strontium is a soft, silvery metal that burns in air and reacts with water. It is found in the minerals celestite and strontianite. Its incorporated into shells of some deep sea
