This property makes uranium hydrides convenient starting materials to create reactive uranium powder along with various uranium carbide, nitride, and halide compounds. The free element, produced by reductive smelting, is a hard, lustrous, silver-gray metal. Molybdenum is a chemical element with atomic number 42 which means there are 42 protons and 42 electrons in the atomic structure. The chemical symbol for Bromine is Br. Melting point of Uranium is 1132°C. 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 Hafnium is Hf. As a solid is heated, its particles vibrate more rapidly as the solid absorbs kinetic energy. Arsenic occurs in many minerals, usually in combination with sulfur and metals, but also as a pure elemental crystal. Name: Uranium Symbol: U Atomic Number: 92 Atomic Mass: 238.0289 amu Melting Point: 1132.0 °C (1405.15 K, 2069.6 °F) Boiling Point: 3818.0 °C (4091.15 K, 6904.4 °F) Number of Protons/Electrons: 92 Number of Neutrons: 146 Classification: Rare Earth Crystal Structure: Orthorhombic Density @ 293 K: 18.95 g/cm 3 Color: silverish Atomic Structure Holmium is a chemical element with atomic number 67 which means there are 67 protons and 67 electrons in the atomic structure. Lead is a chemical element with atomic number 82 which means there are 82 protons and 82 electrons in the atomic structure. These have similar chemical properties, but palladium has the lowest melting point and is the least dense of them. [97] A few solid and semi-metallic compounds such as UO and US exist for the formal oxidation state uranium(II), but no simple ions are known to exist in solution for that state. [99] Reduction of UF4 with hydrogen at 1000 °C produces uranium trifluoride (UF3). Under normal conditions, sulfur atoms form cyclic octatomic molecules with a chemical formula S8. Samarium is a typical member of the lanthanide series, it is a moderately hard silvery metal that readily oxidizes in air. Titanium condenser tubes are usually the best technical choice, however titanium is very expensive material. By mass, oxygen is the third-most abundant element in the universe, after hydrogen and helium. Silicon is a chemical element with atomic number 14 which means there are 14 protons and 14 electrons in the atomic structure. Thorium metal is silvery and tarnishes black when exposed to air, forming the dioxide. Caesium has physical and chemical properties similar to those of rubidium and potassium. Though hydrogen bonds are the strongest of the intermolecular forces, the strength of hydrogen bonds is much less than that of ionic bonds. The chemical symbol for Antimony is Sb. Uranium metal is silver-colored with a gray surface and is nearly as strong as steel.Natural uranium is a mixture of three types or isotopes called U-234/ 234 U, U-235/ 235 U and U-238/ 238 U. The chemical symbol for Vanadium is V. Vanadium is a hard, silvery grey, ductile, and malleable transition metal. Uranium(4) oxide, red. Rubidium is a chemical element with atomic number 37 which means there are 37 protons and 37 electrons in the atomic structure. It is an important nuclear fuel. Adding a heat will convert the solid into a liquid with no temperature change. Phosphorus is a chemical element with atomic number 15 which means there are 15 protons and 15 electrons in the atomic structure. Bismuth is a brittle metal with a silvery white color when freshly produced, but surface oxidation can give it a pink tinge. The chemical symbol for Radon is Rn. Uranium is a silvery-white metal in the actinide series of the periodic table. By mass, aluminium makes up about 8% of the Earth’s crust; it is the third most abundant element after oxygen and silicon and the most abundant metal in the crust, though it is less common in the mantle below. Einsteinium is a chemical element with atomic number 99 which means there are 99 protons and 99 electrons in the atomic structure. Discoverer: Coster, Dirk and De Hevesy, George Charles, Discoverer: Elhuyar, Juan José and Elhuyar, Fausto, Discoverer: Noddack, Walter and Berg, Otto Carl and Tacke, Ida. The chemical symbol for Fluorine is F. Fluorine is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. It is an extremely reactive element and a strong oxidising agent: among the elements, it has the highest electron affinity and the third-highest electronegativity, behind only oxygen and fluorine. There are over 100 different borate minerals, but the most common are: borax, kernite, ulexite etc. Because of its closed-shell electron configuration, its density and melting and boiling points differ significantly from those of most other lanthanides.
