Platinum is a chemical element A chemical element is a pure chemical substance consisting of one type of atom distinguished by its atomic number, which is the number of protons in its nucleus. The term is also used to refer to a pure chemical substance composed of atoms with the same number of protons. Common examples of elements are iron, copper, silver, gold, hydrogen, carbon, with the chemical symbol A chemical symbol is an abbreviation or shortened version of the name of a chemical element generally assigned in relation to its Latin name. Natural elements all have symbols of one or two letters; some man-made elements have temporary symbols of three letters. Each element is usually denoted by the a capital letter, corresponding to the first Pt and an atomic number In chemistry and physics, the atomic number is the number of protons found in the nucleus of an atom and therefore identical to the charge number of the nucleus. It is conventionally represented by the symbol Z. The atomic number uniquely identifies a chemical element. In an atom of neutral charge, the atomic number is also equal to the number of of 78. Its name is derived from the Spanish term platina del Pinto, which is literally translated into "little silver of the Pinto River."[1] It is in Group 10 of the periodic table of elements The periodiс table of the chemical elements is a tabular display of the chemical elements. Although precursors to this table exist, its invention is generally credited to Russian chemist Dmitri Mendeleev in 1869, who intended the table to illustrate recurring ("periodic") trends in the properties of the elements. The layout of the table. A dense The density of a material is defined as its mass per unit volume. The symbol of density is ρ, malleable Ductility is a mechanical property used to describe the extent to which materials can be deformed plastically without fracture, ductile Ductility is a mechanical property used to describe the extent to which materials can be deformed plastically without fracture, precious A precious metal is a rare, naturally occurring metallic chemical element of high economic value, which is not radioactive . Chemically, the precious metals are less reactive than most elements, have high lustre, are softer or more ductile, and have higher melting points than other metals. Historically, precious metals were important as currency,, gray-white transition metal The name transition comes from their position in the periodic table of elements. In each of the four periods in which they occur, these elements represent the successive addition of electrons to the d atomic orbitals of the atoms. In this way, the transition metals represent the transition between group 2 elements and group 13 elements, platinum is resistant to corrosion and occurs in some nickel Nickel is a chemical element, with the chemical symbol Ni and atomic number 28. It is a silvery-white lustrous metal with a slight golden tinge. It is one of the four ferromagnetic elements at about room temperature, other three being iron, cobalt and gadolinium. Its use has been traced as far back as 3500 BC, but it was first isolated and and copper Copper is a chemical element with the symbol Cu (Latin: cuprum) and atomic number 29. It is a ductile metal with very high thermal and electrical conductivity. Pure copper is rather soft and malleable and a freshly-exposed surface has a pinkish or peachy color. It is used as a thermal conductor, an electrical conductor, a building material, and a ores along with some native deposits. Platinum is used in jewelry, laboratory equipment, electrical Electricity is a general term that encompasses a variety of phenomena resulting from the presence and flow of electric charge. These include many easily recognizable phenomena, such as lightning and static electricity, but in addition, less familiar concepts, such as the electromagnetic field and electromagnetic induction contacts and electrodes An electrode is an electrical conductor used to make contact with a nonmetallic part of a circuit . The word was coined by the scientist Michael Faraday from the Greek words elektron (meaning amber, from which the word electricity is derived) and hodos, a way, platinum resistance thermometers Resistance thermometers, also called resistance temperature detectors or resistive thermal devices , are temperature sensors that exploit the predictable change in electrical resistance of some materials with changing temperature. As they are almost invariably made of platinum, they are often called platinum resistance thermometers (PRTs). They, dentistry Dentistry is the known evaluation, diagnosis, prevention, and treatment of diseases, disorders and conditions of the soft and hard tissues of the jaw , the oral cavity, maxillofacial area and the adjacent and associated structures and their impact on the human body. Dentistry is a part of stomatology. Dentistry is widely considered necessary for equipment, and catalytic converters A catalytic converter is a device used to reduce the toxicity of emissions from an internal combustion engine. First widely introduced on series-production automobiles in the U.S. market for the 1975 model year to comply with tightening EPA regulations on auto exhaust, catalytic converters are still most commonly used in motor vehicle exhaust. Platinum bullion A precious metal is a rare, naturally occurring metallic chemical element of high economic value, which is not radioactive . Chemically, the precious metals are less reactive than most elements, have high lustre, are softer or more ductile, and have higher melting points than other metals. Historically, precious metals were important as currency, has the ISO currency code ISO 4217 is the international standard describing three-letter codes to define the names of currencies established by the International Organization for Standardization (ISO). The ISO 4217 code list is the established norm in banking and business all over the world for defining different currencies, and in many countries the codes for the more of XPT. Platinum is a commodity with a value that fluctuates according to market forces. As of 8 March 2010)[update], platinum was worth US$ The United States dollar is the unit of currency of the United States. The U.S. dollar is normally abbreviated as the dollar sign, $, or as USD or US$ to distinguish it from other dollar-denominated currencies and from others that use the $ symbol. It is divided into 100 cents (200 half-cents prior to 1857)51.89 per gram The gram , (Greek/Latin root grámma); symbol g, is a unit of mass (US$ The United States dollar is the unit of currency of the United States. The U.S. dollar is normally abbreviated as the dollar sign, $, or as USD or US$ to distinguish it from other dollar-denominated currencies and from others that use the $ symbol. It is divided into 100 cents (200 half-cents prior to 1857)1,614.00 per troy ounce The troy ounce is a unit of imperial measure. In the present day it is most commonly used to gauge the weight and therefore the price of precious metals. One troy ounce is equivalent to 31.1034768 grams).[2]
