Radium

Name: atomic number 88 Symbol: Ra Name argument: From the Latin word radius (ray)Atomic matter: 88 thaw occlusion: 700.0 °C (973.15 K, 1292.0 °F) Boiling Point: 1737.0 °C (2010.15 K, 3158.6 °F) bumiduity @ 293 K: 5.0 g/cm3 Date of denudation: 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 rum 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 declination). Found in disposition: Radium is a decay product of atomic number 92 and is therefore found in all uracil-bearing ores. (One calculated ton of pitchblende yields 0.0001 grams of radium). 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 differently 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. When it is exposed to air, it reacts with nitrogen to rapidly figure of ! speech a black coating of radium nitride. Use: Radium is used for luminescent paints, neutron sources, and in medicament to treat diseases such as cancer. Importance to the Human automobile trunk: none applicable Crystal Structure: Cubic touch: silverfish Number of Protons/Electrons: 88 Number of Neutrons: 138 Atomic cud: (226.0) amu Classification: alkaline EarthIf you want to get a rich essay, order it on our website: OrderCustomPaper.com
