Radium

Name: atomic keep down 88 Symbol: Ra Name argument: From the Latin word radius (ray)Atomic takings: 88 thaw institutionalise: 700.0 °C (973.15 K, 1292.0 °F) Boiling Point: 1737.0 °C (2010.15 K, 3158.6 °F) dirty dogiduity @ 293 K: 5.0 g/cm3 Date of husking: 1898 Discovered By: Pierre and Marie curie How it was Discovered: celestial longitude was discovered because Marie Curie and her husband and research partner Pierre, were suspicious about the constitution of pitchblende. In their efforts to investigate the elements that made up this complex mineral, they discovered eminations (which were the results of radioactive declivity). Found in record: Radium is a decay product of atomic number 92 and is therefore found in all atomic number 92-bearing ores. (One mensurable ton of pitchblende yields 0.0001 grams of right ascension). Radium was originally acquired from pitchblende ore from Joachimsthal, Bohemia, in the Czech Republic. Carnotite sands in atomic number 27 provide some of the element, but richer ores are found in the Democratic Republic of the Congo and the Great Lakes area of Canada, and ass also be extracted from uranium processing waste.

Large radium-containing uranium deposits are located in Canada (Ontario), the United States (New Mexico, Utah, and Virginia), Australia, and in otherwise places Characteristics: Radium is a silvery-white metallic element. It is highly radioactive and its decay product, registered nurse gas, is also radioactive. One result of radiums intense radioactivity is that the metal and its compounds glow in the dark. W hen it is exposed to air, it reacts with nit! rogen to rapidly figure of speech a black coating of radium nitride. Use: Radium is used for luminescent paints, neutron sources, and in medicinal drug to treat diseases such as cancer. Importance to the Human form: none applicable Crystal Structure: Cubic intensity: silverfish Number of Protons/Electrons: 88 Number of Neutrons: 138 Atomic mint candy: (226.0) amu Classification: alkaline EarthIf you want to get a adept essay, order it on our website: OrderCustomPaper.com
