Iron is a metal in the first transition series. Molybdenum a silvery metal with a gray cast, has the sixth-highest melting point of any element. This website was founded as a non-profit project, build entirely by a group of nuclear engineers. 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 atom—the Na+ cation. Notes on the Melting Point of particular elements: Helium: Helium does not solidify at standard pressure. Thorium is a naturally-occurring element and it is estimated to be about three times more abundant than uranium. Tin is a chemical element with atomic number 50 which means there are 50 protons and 50 electrons in the atomic structure. Tin is a post-transition metal in group 14 of the periodic table. The chemical symbol for Bromine is Br. Because of its closed-shell electron configuration, its density and melting and boiling points differ significantly from those of most other lanthanides. Aluminium is a silvery-white, soft, nonmagnetic, ductile metal in the boron group. Mercury is a heavy, silvery d-block element, mercury is the only metallic element that is liquid at standard conditions for temperature and pressure. Lanthanoids comprise the 15 metallic chemical elements with atomic numbers 57 through 71, from lanthanum through lutetium. Ruthenium is a rare transition metal belonging to the platinum group of the periodic table. The chemical symbol for Thorium is Th. Lead is soft and malleable, and has a relatively low melting point. Pure radium is silvery-white alkaline earth metal. The name xenon for this gas comes from the Greek word ξένον [xenon], neuter singular form of ξένος [xenos], meaning ‘foreign(er)’, ‘strange(r)’, or ‘guest’. Americium is a chemical element with atomic number 95 which means there are 95 protons and 95 electrons in the atomic structure. Impurities present in any metals elevates its melting point. The chemical symbol for Uranium is U. This website does not use any proprietary data. Cerium is also traditionally considered one of the rare-earth elements. Melting and Boiling Points of the Platinum Group Metals (°C) (34, 35) Current Methods for Melting the PGMs Early methods for melting the pgms used blowpipe procedures, while Daniell used electricity. More durable and stable. Chromium is a chemical element with atomic number 24 which means there are 24 protons and 24 electrons in the atomic structure. Uranium has the highest atomic weight of the primordially occurring elements. Neodymium is a soft silvery metal that tarnishes in air. Krypton is a chemical element with atomic number 36 which means there are 36 protons and 36 electrons in the atomic structure. Archaeologists have discovered traces of platinum in the gold used in ancient Egyptian burials as early as 1200 BC. Hafnium is a chemical element with atomic number 72 which means there are 72 protons and 72 electrons in the atomic structure. Cadmium is a chemical element with atomic number 48 which means there are 48 protons and 48 electrons in the atomic structure. The chemical symbol for Mercury is Hg. Uranium is weakly radioactive because all isotopes of uranium are unstable, with half-lives varying between 159,200 years and 4.5 billion years. Nobelium is the tenth transuranic element and is the penultimate member of the actinide series. Covalent bonds often result in the formation of small collections of better-connected atoms called molecules, which in solids and liquids are bound to other molecules by forces that are often much weaker than the covalent bonds that hold the molecules internally together. It is obtained chiefly from the mineral cassiterite, which contains tin dioxide. Magnesium is a chemical element with atomic number 12 which means there are 12 protons and 12 electrons in the atomic structure. The chemical symbol for Promethium is Pm. The chemical symbol for Iodine is I. Iodine is the heaviest of the stable halogens, it exists as a lustrous, purple-black metallic solid at standard conditions that sublimes readily to form a violet gas. The chemical symbol for Californium is Cf. The chemical symbol for Aluminum is Al. The chemical symbol for Palladium is Pd. Our Website follows all legal requirements to protect your privacy. Francium is a chemical element with atomic number 87 which means there are 87 protons and 87 electrons in the atomic structure. Silver is a soft, white, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal. In the periodic table, potassium is one of the alkali metals. Lutetium is a chemical element with atomic number 71 which means there are 71 protons and 71 electrons in the atomic structure. Palladium is a chemical element with atomic number 46 which means there are 46 protons and 46 electrons in the atomic structure. Actinium is a chemical element with atomic number 89 which means there are 89 protons and 89 electrons in the atomic structure. The commercial use of beryllium requires the use of appropriate dust control equipment and industrial controls at all times because of the toxicity of inhaled beryllium-containing dusts that can cause a chronic life-threatening allergic disease in some people called berylliosis. Melting Point of Platinum The ratio of the pressure of a gas at the melting point of platinum to its pressure at the triple point of water, when the … The chemical symbol for Carbon is C. It is nonmetallic and tetravalent—making four electrons available to form covalent chemical bonds.
