During electrorefining of copper, noble metals such as silver, gold and the platinum-group metals as well as selenium and tellurium settle to the bottom of the cell as "anode mud", which forms the starting point for the extraction of the platinum-group metals. Allene-derived gold and platinum complexes: synthesis and first applications in catalysis. It is occasionally found in native form as elemental crystals. Platinum is one of the least reactive metals. The chemical symbol for Niobium is Nb. Being a heavy metal, it leads to health problems upon exposure to its salts; but due to its corrosion resistance, metallic platinum has not been linked to adverse health effects. © 2019 / see also Its density is about 70% higher than that of lead, and slightly lower than that of gold or tungsten.

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. Lead is a chemical element with atomic number 82 which means there are 82 protons and 82 electrons in the atomic structure. The chemical symbol for Phosphorus is P. As an element, phosphorus exists in two major forms—white phosphorus and red phosphorus—but because it is highly reactive, phosphorus is never found as a free element on Earth. It is also sometimes considered the first element of the 6th-period transition metals and is traditionally counted among the rare earth elements. Being a typical member of the lanthanide series, europium usually assumes the oxidation state +3. Copernicium - Atomic Mass - Atomic Weight - Cn, Iridium - Atomic Mass - Atomic Weight - Ir, Osmium - Atomic Mass - Atomic Weight - Os, Actinium - Atomic Mass - Atomic Weight - Ac, Polonium - Atomic Mass - Atomic Weight - Po, Arsenic - Atomic Mass - Atomic Weight - As, Iridium – Atomic Mass – Atomic Weight – Ir. Nickel belongs to the transition metals and is hard and ductile. Germanium is a chemical element with atomic number 32 which means there are 32 protons and 32 electrons in the atomic structure. Heating this ammonium salt in the presence of hydrogen reduces it to elemental platinum. Neodymium is not found naturally in metallic form or unmixed with other lanthanides, and it is usually refined for general use. It is a noble metal and a member of the platinum group. The atomic weights used on this site come from NIST, the National Institute of Standards and Technology. Under standard conditions, it is the lightest metal and the lightest solid element. When calculating molecular weight of a chemical compound, it tells us how many grams are in one mole of that substance. Scheffer described platinum as being less pliable than gold, but with similar resistance to corrosion. It is also the most corrosion-resistant metal, even at temperatures as high as 2000 °C. Atomic mass of Platinum is 195.078 u. These relative weights computed from the chemical equation are sometimes called equation weights. Of the naturally occurring isotopes, only 190Pt is unstable, though it decays with a half-life of 6.5×1011 years, causing an activity of 15 Bq/kg of natural platinum. The atomic mass is the mass of an atom. Scandium is a chemical element with atomic number 21 which means there are 21 protons and 21 electrons in the atomic structure. Like all elements with atomic number over 100, lawrencium can only be produced in particle accelerators by bombarding lighter elements with charged particles. The chemical symbol for Cerium is Ce. In 1752, Henrik Scheffer published a detailed scientific description of the metal, which he referred to as "white gold", including an account of how he succeeded in fusing platinum ore with the aid of arsenic. Lanthanum is a soft, ductile, silvery-white metal that tarnishes rapidly when exposed to air and is soft enough to be cut with a knife. Their assumptions could not be avoided because the platinum they experimented with was highly contaminated with minute amounts of platinum-family elements such as osmium and iridium, amongst others, which embrittled the platinum alloy. Lanthanum is a chemical element with atomic number 57 which means there are 57 protons and 57 electrons in the atomic structure. Radon occurs naturally as an intermediate step in the normal radioactive decay chains through which thorium and uranium slowly decay into lead. The chemical symbol for Nickel is Ni.

How weight affects the price of Gold over Platinum. The chemical symbol for Gold is Au. Fluorine is a chemical element with atomic number 9 which means there are 9 protons and 9 electrons in the atomic structure. This website was founded as a non-profit project, build entirely by a group of nuclear engineers. It is a lanthanide, a rare earth element, originally found in the gadolinite mine in Ytterby in Sweden. The chemical element Platinum is a lustrous silvery-white, malleable, ductile transition metal.Its atomic number is 78 and represented by the symbol Pt. It has six naturally occurring isotopes. The atomic mass is the mass of an atom. Silver is a soft, white, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal. The chemical symbol for Uranium is U. Platinum is used in catalytic converters, laboratory equipment, electrical contacts and electrodes, platinum resistance thermometers, dentistry equipment, and jewelry. Praseodymium is a soft, silvery, malleable and ductile metal, valued for its magnetic, electrical, chemical, and optical properties.
