Text © The Royal Society of Chemistry 1999-2011 It is a lanthanide, a rare earth element, originally found in the gadolinite mine in Ytterby in Sweden. Titanium condenser tubes are usually the best technical choice, however titanium is very expensive material. Because of this, the first two rows of the periodic table are labeled the s block. The name samarium is after the mineral samarskite from which it was isolated. The chemical symbol for Bismuth is Bi. Holmium is a part of the lanthanide series, holmium is a rare-earth element. Electron configuration of Silver is [Kr] 4d10 5s1. Zirconium is mainly used as a refractory and opacifier, although small amounts are used as an alloying agent for its strong resistance to corrosion. Thorium is a naturally-occurring element and it is estimated to be about three times more abundant than uranium. However, it is mostly extracted from lead-zinc, copper, gold and copper-nickel ores as a by-product of mining for these metals. The metal reacts with sulphur in the air, rapidly forming a dull, dark silver sulphide tarnish that has to be polished off. Political stability of top reserve holder. Electronic Configuration. Yttrium is a chemical element with atomic number 39 which means there are 39 protons and 39 electrons in the atomic structure. Atoms of the same element with different numbers of neutrons. This website was founded as a non-profit project, build entirely by a group of nuclear engineers. The periodic table is a tabular display of the chemical elements organized on the basis of their atomic numbers, electron configurations, and chemical properties. Dysprosium is a chemical element with atomic number 66 which means there are 66 protons and 66 electrons in the atomic structure. Rhenium is a chemical element with atomic number 75 which means there are 75 protons and 75 electrons in the atomic structure. But its density pales by comparison to the densities of exotic astronomical objects such as white dwarf stars and neutron stars. The chemical symbol for Osmium is Os. Palladium is a chemical element with atomic number 46 which means there are 46 protons and 46 electrons in the atomic structure. A photon of light hitting the negative nitrate anion frees an electron, which ultimately combines with the positive silver ions to make neutral silver metal, darkening the surface of the material. The chemical symbol for Helium is He. Sterling silver contains 92.5% silver. Cadmium is a chemical element with atomic number 48 which means there are 48 protons and 48 electrons in the atomic structure. This Site has been carefully prepared for your visit, and we ask you to honour and agree to the following terms and conditions when using this Site. Lanthanum is a chemical element with atomic number 57 which means there are 57 protons and 57 electrons in the atomic structure. Neon is a chemical element with atomic number 10 which means there are 10 protons and 10 electrons in the atomic structure. It is also the most corrosion-resistant metal, even at temperatures as high as 2000 °C. Helium is a chemical element with atomic number 2 which means there are 2 protons and 2 electrons in the atomic structure. Actinium is a soft, silvery-white radioactive metal. 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. It is given by the ratio of the pressure on a body to the fractional decrease in volume.

It is fairly soft and slowly tarnishes in air. Thorium metal is silvery and tarnishes black when exposed to air, forming the dioxide. For example, silicon has nine possible integer oxidation states from −4 to +4, but only -4, 0 and +4 are common oxidation states. Zirconium is a lustrous, grey-white, strong transition metal that resembles hafnium and, to a lesser extent, titanium. The bulk properties of astatine are not known with any certainty. The chemical symbol for Francium is Fr. The mass of an atom relative to that of carbon-12. Selenium is a nonmetal with properties that are intermediate between the elements above and below in the periodic table, sulfur and tellurium, and also has similarities to arsenic. Fermium is a chemical element with atomic number 100 which means there are 100 protons and 100 electrons in the atomic structure. Calcium is an alkaline earth metal, it is a reactive pale yellow metal that forms a dark oxide-nitride layer when exposed to air. The electron configuration is the distribution of electrons of an atom or molecule (or other physical structure) in atomic or molecular orbitals. Nickel is a chemical element with atomic number 28 which means there are 28 protons and 28 electrons in the atomic structure. Neptunium metal is silvery and tarnishes when exposed to air. Barium is the fifth element in group 2 and is a soft, silvery alkaline earth metal. Mercury is commonly known as quicksilver and was formerly named hydrargyrum. Welcome to Chemistry in its element. The chemical properties of this silvery gray, crystalline transition metal are intermediate between rhenium and manganese. Currency – still in some countries silver coins are used as currency. Niobium is a soft, grey, ductile transition metal, often found in the minerals pyrochlore (the main commercial source for niobium) and columbite. Lawrencium is the final member of the actinide series. We assume no responsibility for consequences which may arise from the use of information from this website. Caesium is a soft, silvery-gold alkali metal with a melting point of 28.5 °C, which makes it one of only five elemental metals that are liquid at or near room temperature. It is also a good conductor, but expensive. Carbon is one of the few elements known since antiquity. Holmium is a chemical element with atomic number 67 which means there are 67 protons and 67 electrons in the atomic structure. Lead is widely used as a gamma shield. It is also used in dental alloys, solder and brazing alloys, electrical contacts and batteries. Francium is a highly radioactive metal that decays into astatine, radium, and radon.
