Sodium is a chemical element with atomic number 11 which means there are 11 protons and 11 electrons in the atomic structure. Dysprosium is used for its high thermal neutron absorption cross-section in making control rods in nuclear reactors, for its high magnetic susceptibility in data storage applications. (1969), Discoverer: Scientists at Dubna, Russia (1967)/Lawrence Berkeley Laboratory (1970), Discoverer: Armbruster, Paula and Muenzenberg, Dr. Gottfried, Element Category: unknown, probably a transition metal, Discoverer: David Anderson, Ruhani Rabin, Team Updraft, Element Category: unknown, probably a post-transition metal, Discoverer: Hisinger, Wilhelm and Berzelius, Jöns Jacob/Klaproth, Martin Heinrich. Discoverer: Corson, Dale R. and Mackenzie, K. R. The actinide or actinoid series encompasses the 15 metallic chemical elements with atomic numbers from 89 to 103, actinium through lawrencium. The chemical symbol for Neodymium is Nd. All isotopes of radium are highly radioactive, with the most stable isotope being radium-226. In nuclear industry, especially artificial xenon 135 has a tremendous impact on the operation of a nuclear reactor. The chemical symbol for Polonium is Po. Scandium is a silvery-white metallic d-block element, it has historically been sometimes classified as a rare-earth element, together with yttrium and the lanthanides. Design custom worksheets in 5 … This type of respiration occurs in three steps: glycolysis; the Krebs cycle; and electron transport phosphorylation. The chemical symbol for Oxygen is O. Platinum is a dense, malleable, ductile, highly unreactive, precious, silverish-white transition metal. Chemically, indium is similar to gallium and thallium. A:, 1985, 32, 1890. The chemical properties of the atom are determined by the number of protons, in fact, by number and arrangement of electrons. The chemical symbol for Nitrogen is N. Nitrogen is a colourless, odourless unreactive gas that forms about 78% of the earth’s atmosphere. The chemical symbol for Osmium is Os. Symbol: O. It provides energy levels for atomic nuclei of the isotope O-21 (oxygen, atomic number Z = 8, mass number A = 21).
