TheÂ chemical symbolÂ for Krypton isÂ Kr. Each nuclide is denoted by chemical symbol of the element (this specifies Z) with tha atomic mass number as supescript. These two forces compete, leading to various stability of nuclei. TheÂ chemical symbolÂ for Nobelium isÂ No. Sodium is an alkali metal, being in group 1 of the periodic table, because it has a single electron in its outer shell that it readily donates, creating a positively charged atomâthe Na+ cation. It is extensively used in a large variety of industrial branches, from chemical industry (producing fertilizers, etc) to electronic (substance producing) and food industry, etc. These condensers use tubes that are usually made of stainless steel, copper alloys, or titanium depending on several selection criteria (such as thermal conductivity or corrosion resistance). Technetium is the lightest element whose isotopes are all radioactive; none are stable. TheÂ chemical symbolÂ for Terbium isÂ Tb. Actinium is a soft, silvery-white radioactive metal. Our Website follows all legal requirements to protect your privacy. TheÂ chemical symbolÂ for Gold isÂ Au. Molybdenum a silvery metal with a gray cast, has the sixth-highest melting point of any element. The excess neutrons act somewhat like nuclear glue.Â Only two stable nuclides have fewer neutrons than protons: hydrogen-1 and helium-3. Since hydrogen is a part of water molecule, it is an absolutely essential chemical element for life, which can be found in all living bodies on our planet. Germanium is a lustrous, hard, grayish-white metalloid in the carbon group, chemically similar to its group neighbors tin and silicon. TheÂ chemical symbolÂ for Indium isÂ In. It was first synthesized in 2003 by a group of Russian, Japanese and French scientists at RIKEN’s RI Beam Science Laboratory, by bombarding hydrogen with helium-8 atoms. TheÂ chemical symbolÂ for Hydrogen isÂ H. Mass numbers of typical isotopes ofÂ HydrogenÂ areÂ 1; 2. OsmiumÂ is a chemical element withÂ atomic numberÂ 76Â which means there are 76 protons and 76 electrons in the atomic structure. Sodium is a soft, silvery-white, highly reactive metal. The ninth member of the lanthanide series, terbium is a fairly electropositive metal that reacts with water, evolving hydrogen gas. Promethium is one of only two such elements that are followed in the periodic table by elements with stable forms. Nickel belongs to the transition metals and is hard and ductile. In nuclear industry gadolinium is commonly used as a neutron absorber due to very high neutron absorbtion cross-section of two isotopes 155Gd and 157Gd. Only about 5Ã10â8% of all matter in the universe is europium. Note that, eachÂ elementÂ may contain moreÂ isotopes, therefore this resulting atomic mass is calculated from naturally-occuring isotopes and their abundance. Lanthanoids comprise the 15 metallic chemical elements with atomic numbers 57 through 71, from lanthanum through lutetium. VanadiumÂ is a chemical element withÂ atomic numberÂ 23Â which means there are 23 protons and 23 electrons in the atomic structure. Chemically, deuterium behaves similarly to ordinary hydrogen (protium), but there are differences in bond energy and length for compounds of heavy hydrogen isotopes, which are larger than the isotopic differences in any other element. Platinum is used in catalytic converters, laboratory equipment, electrical contacts and electrodes, platinum resistance thermometers, dentistry equipment, and jewelry. The chemical properties of this silvery gray, crystalline transition metal are intermediate between rhenium and manganese. HafniumÂ is a chemical element withÂ atomic numberÂ 72Â which means there are 72 protons and 72 electrons in the atomic structure.
