Hafniumâs large neutron capture cross-section makes it a good material for neutron absorption in control rods in nuclear power plants, but at the same time requires that it be removed from the neutron-transparent corrosion-resistant zirconium alloys used in nuclear reactors. Atomic Number â Does it conserve in a nuclear reaction? Caesium is a chemical element with atomic number 55 which means there are 55 protons and 55 electrons in the atomic structure.

When considered as the temperature of the reverse change from vapor to liquid, it is referred to as the condensation point. Discoverer: Priestley, Joseph and Scheele, Carl Wilhelm, Discoverer: Ramsay, William and Travers, Morris, Discoverer: Ramsay, Sir William and Strutt, John (Lord Rayleigh), Discoverer: Del Rio, Andrés Manuel (1801) and Sefström, Nils Gabriel (1830), Discoverer: Lecoq de Boisbaudran, Paul-Ãmile, Discoverer: Ramsay, Sir William and Travers, Morris, Discoverer: Bunsen, Robert Wilhelm and Kirchhoff, Gustav Robert, Discoverer: Perrier, Carlo and Segrè, Emilio, Discoverer: Reich, Ferdinand and Richter, Hieronymus, Discoverer: Müller von Reichenstein, Franz Joseph, Discoverer: Ramsay, William and Travers, Morris William, Discoverer: Kirchhoff, Gustav and Bunsen, Robert. The chemical symbol for Ytterbium is Yb. Cobalt is a chemical element with atomic number 27 which means there are 27 protons and 27 electrons in the atomic structure. Since the density (Ï) of a substance is the total mass (m) of that substance divided by the total volume (V) occupied by that substance, it is obvious, the density of a substance strongly depends on its atomic mass and also on the atomic number density (N; atoms/cm3). Zirconium is a lustrous, grey-white, strong transition metal that resembles hafnium and, to a lesser extent, titanium. Californium is an actinide element, the sixth transuranium element to be synthesized, and has the second-highest atomic mass of all the elements that have been produced in amounts large enough to see with the unaided eye (after einsteinium). The electron affinities will become less negative as you go from the top to the bottom of the periodic table. Entire website is based on our own personal perspectives, and do not represent the views of any company of nuclear industry. Neon is a colorless, odorless, inert monatomic gas under standard conditions, with about two-thirds the density of air. The chemical symbol for Dysprosium is Dy. As with boiling points, the melting point of a solid is dependent on the strength of those attractive forces. Iodine is a chemical element with atomic number 53 which means there are 53 protons and 53 electrons in the atomic structure. Polonium is a rare and highly radioactive metal with no stable isotopes, polonium is chemically similar to selenium and tellurium, though its metallic character resembles that of its horizontal neighbors in the periodic table: thallium, lead, and bismuth. It is the fifth most abundant element in Earthâs crust and the third most abundant metal, after iron and aluminium. Electron configuration of Carbon is [He] 2s2 2p2. Most elements have more than one possible oxidation state. The chemical symbol for Neptunium is Np. Germanium is a lustrous, hard, grayish-white metalloid in the carbon group, chemically similar to its group neighbors tin and silicon. It occurs in many forms. Oxidation states are typically represented by integers which may be positive, zero, or negative. All isotopes of radium are highly radioactive, with the most stable isotope being radium-226. The chemical symbol for Carbon is C. It is nonmetallic and tetravalent—making four electrons available to form covalent chemical bonds. Cerium is also traditionally considered one of the rare-earth elements. In the periodic table, potassium is one of the alkali metals. The ninth member of the lanthanide series, terbium is a fairly electropositive metal that reacts with water, evolving hydrogen gas. The chemical symbol for Rhodium is Rh. The chemical symbol for Carbon is C. It is nonmetallic and tetravalentâmaking four electrons available to form covalent chemical bonds. Therefore the electronegativity is greatest at the top-right of the periodic table and decreases toward the bottom-left. Argon is the third-most abundant gas in the Earthâs atmosphere, at 0.934% (9340 ppmv). Elemental sulfur is a bright yellow crystalline solid at room temperature. Increasing the pressure on an material (especially for liquids or gases) decreases the volume of the object and thus increases its density via the atomic number density. The standard SI unit is kilograms per cubic meter (kg/m3). The chemical symbol for Indium is In. The melting point also defines a condition in which the solid and liquid can exist in equilibrium.
