Radium

Name: atomic enumerate 88 Symbol: Ra Name argument: From the Latin word radius (ray)Atomic issue: 88 thaw blame: 700.0 °C (973.15 K, 1292.0 °F) Boiling Point: 1737.0 °C (2010.15 K, 3158.6 °F) goatiduity @ 293 K: 5.0 g/cm3 Date of discovery: 1898 Discovered By: Pierre and Marie curie How it was Discovered: atomic number 88 was discovered because Marie Curie and her husband and research partner Pierre, were leftover 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 decomposition reaction). Found in temperament: Radium is a decay product of atomic number 92 and is therefore found in all uracil-bearing ores. (One mensural 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 irradiation is that the metal and its compounds glow in the dark. When it is exposed to air, it reacts with nitrogen to chop-ch! op 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 physical structure: none applicable Crystal Structure: Cubic emblazon: silverfish Number of Protons/Electrons: 88 Number of Neutrons: 138 Atomic muckle: (226.0) amu Classification: alkaline EarthIf you want to get a full moon essay, order it on our website: OrderCustomPaper.com
