Platinum ( /ˈplætɨnəm/ or /ˈplætənəm/) is a chemical element with the chemical symbol Pt and an atomic number of 78.

Its name is derived from the Spanish term platina, which is literally translated into "little silver". It is a dense, malleable, ductile, precious, gray-white transition metal.

Even though it has six naturally occurring isotopes, platinum is one of the rarest elements in the Earth's crust and has an average abundance of approximately 5 μg/kg. It is the least reactive metal. It occurs in some nickel and copper ores along with some native deposits, mostly in South Africa, which accounts for 80% of the world production.

As a member of the platinum group of elements, as well as of the group 10 of the periodic table of elements, platinum is generally non-reactive. It exhibits a remarkable resistance to corrosion, even at high temperatures, and as such is considered a noble metal. As a result, platinum is often found chemically uncombined as native platinum. Because it occurs naturally in the alluvial sands of various rivers, it was first used by pre-Columbian South American natives to produce artifacts. It was referenced in European writings as early as 16th century, but it was not until Antonio de Ulloa published a report on a new metal of Colombian origin in 1748 that it became investigated by scientists.

Miranda Leigh Shelton (née Lambert) (born November 10, 1983) is an American country music artist who gained fame as a finalist on the 2003 season of Nashville Star, where she finished in third place and later signed to Epic Records. Lambert made her debut with the release of "Me and Charlie Talking", the first single from her 2005 debut album Kerosene. This album, which was certified Platinum in the United States, also produced the singles "Bring Me Down", "Kerosene", and "New Strings". All four singles were Top 40 hits on the Billboard Hot Country Songs charts.

After Epic's Nashville division closed, Lambert was transferred to Columbia Records Nashville for her second album, Crazy Ex-Girlfriend, which was released in early 2007. Although the title track failed to make top 40, the next three singles ("Famous in a Small Town", "Gunpowder & Lead", and "More Like Her") were all Top 20 hits, with "Gunpowder & Lead" becoming her first Top 10 country hit in July 2008. Lambert's third album, Revolution, was released in September 2009. Five singles have been released from the album, including Lambert's two Number One hits "The House That Built Me," which spent four weeks at the top of the chart, and "Heart Like Mine". Lambert has also been honored by the Grammy Awards, the Academy of Country Music Awards, and the Country Music Association Awards.
