About This Site    Crystal Structure, Element Groups: 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. It is a noble metal and a member of the platinum group.  Links, Show Table With: The chemical symbol for Rubidium is Rb. The chemical symbol for Tellurium is Te. The systematic element name is a temporary name that is based on the atomic number as a root and the -ium ending as a suffix. Discoverer: Corson, Dale R. and Mackenzie, K. R. The actinide or actinoid series encompasses the 15 metallic chemical elements with atomic numbers from 89 to 103, actinium through lawrencium. Zirconium is a lustrous, grey-white, strong transition metal that resembles hafnium and, to a lesser extent, titanium. Under normal conditions, sulfur atoms form cyclic octatomic molecules with a chemical formula S8. Hydrogen is a chemical element with atomic number 1 which means there are 1 protons and 1 electrons in the atomic structure. Potassium, found in most soils, is an element that is … is a rare earth element with a metallic silver luster. It has remarkable resistance to corrosion, even at high temperatures, and is therefore considered a noble metal. Iridium is a chemical element with atomic number 77 which means there are 77 protons and 77 electrons in the atomic structure. Atomic Number – Does it conserve in a nuclear reaction? The elemental metal is rarely found in nature, but once isolated artificially, the formation of an oxide layer (passivation) stabilizes the free metal somewhat against further oxidation. The chemical symbol for Thulium is Tm. Tungsten is an intrinsically brittle and hard material, making it difficult to work. Lutetium is the last element in the lanthanide series, and it is traditionally counted among the rare earths. Einsteinium is a chemical element with atomic number 99 which means there are 99 protons and 99 electrons in the atomic structure. Potassium is an element in the first group of periodic table and its symbol is K, derived from the Latin word Kalium. Boron is a chemical element with atomic number 5 which means there are 5 protons and 5 electrons in the atomic structure. This fact has key implications for the building up of the periodic table of elements. Actinium gave the name to the actinide series, a group of 15 similar elements between actinium and lawrencium in the periodic table. Neodymium is a soft silvery metal that tarnishes in air. 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). Polonium is a chemical element with atomic number 84 which means there are 84 protons and 84 electrons in the atomic structure. The chemical symbol for Potassium is K. Potassium was first isolated from potash, the ashes of plants, from which its name derives. The chemical symbol for Nickel is Ni. The chemical symbol for Uranium is U. Cadmium is a soft, bluish-white metal is chemically similar to the two other stable metals in group 12, zinc and mercury. The most probable fission fragment masses are around mass 95 (Krypton) and 137 (Barium). Potassium-41 Information Potassium is a soft silvery metallic element belonging to group 1 of the periodic table (alkali metals). Commercially, thallium is produced as a byproduct from refining of heavy metal sulfide ores. Tellurium is chemically related to selenium and sulfur. Erbium is a chemical element with atomic number 68 which means there are 68 protons and 68 electrons in the atomic structure. Discovered in 1807 by Davy, who obtained it from caustic potash (KOH); this was the first metal isolated by electrolysis. Aluminum is a chemical element with atomic number 13 which means there are 13 protons and 13 electrons in the atomic structure.
