The chemical symbol for Nobelium is No. At the same time, the first tungsten steels are being made in Austria. Classification: Tungsten is a transition metal : Color: silvery-white : Atomic weight: 183.84 : State: solid : Melting point: 3422 o C, 3695 K : Boiling point: 5550 o C, 5823 K : . 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. Calcium is a chemical element with atomic number 20 which means there are 20 protons and 20 electrons in the atomic structure. Sodium is a soft, silvery-white, highly reactive metal. Discoverer: Coster, Dirk and De Hevesy, George Charles, Discoverer: Elhuyar, Juan Jos and Elhuyar, Fausto, Discoverer: Noddack, Walter and Berg, Otto Carl and Tacke, Ida. Curium is a hard, dense, silvery metal with a relatively high melting point and boiling point for an actinide. and Gay-Lussac, L.-J. In 1758, the Swedish chemist and mineralogist Axel Fredrik Cronstedt discovered a mineral called tungsten, which means heavy stone in Swedish. Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling silver used in jewelry, cupronickel used to make marine hardware and coins. Required fields are marked *. Helium is a chemical element with atomic number 2 which means there are 2 protons and 2 electrons in the atomic structure.
