Platinum has broad chemical resistance although the metal may be dissolved in aqua regia, a highly acidic mixture of nitric and hydrochloric acids, forming chloroplatinic acid, and has an extremely high melting point in excess of two thousand degrees centigrade.Platinum's properties allowed it to defy identification and classification until the 18In 1859, a method for melting up to 15 kilograms of platinum using a furnace lined with lime and oxygen and coal gas as fuel was described by Deville and Debray.
Platinum is a member of the platinum group of elements and group 10 of the periodic table of elements. It does not oxidize in air even at high temperatures and is unaffected by common acids. The location of the platinum group metals in the periodic table of the elements. He describes it as a strange metal found in mines between Panama and Mexico and wrote that no fire or any of the Spanish arts could melt it.In 1783 French chemist Francois Chabaneaus discovered and patented a method of producing workable platinum.

Platinum metal is silvery white and does not oxidise, properties that make it highly appealing for jewellery. Members of a group typically have similar properties and electron configurations in their outer shell.A horizontal row in the periodic table.
It does not oxidize in air at any temperature, although it is corroded by cyanides, halogens, sulfur, and caustic alkalis.
The chemical element platinum is classed as a transition metal. This accounts for about 50% of demand each year. Platinum does not dissolve in hydrochloric or nitric acid but will dissolve when the two acids are mixed to form aqua regia. Values are given for typical oxidation number and coordination.The energy released when an electron is added to the neutral atom and a negative ion is formed.The tendency of an atom to attract electrons towards itself, expressed on a relative scale.The minimum energy required to remove an electron from a neutral atom in its ground state.The oxidation state of an atom is a measure of the degree of oxidation of an atom.

View videos about Platinum was used in relatively pure form by the pre-Columbian Native Americans. Osmium is the densest naturally occurring element, with an experimentally measured (using x-ray crystallography) density of 22.59 g/cm 3. Platinum is also used to make optical fibres and LCDs, turbine blades, spark plugs, pacemakers and dental fillings.Platinum compounds are important chemotherapy drugs used to treat cancers.
