Platinum-Pt Atomic # 78 Atomic Mas-195.078 Melting Point-1768.3 Celsius Boiling Point-3825 celcius Protons-78 Neutron-117 Electrons-78 Bohr Model Specific Gravity-21.51 Orbital notation and Electron configuration- [Xe] 4f14 5d9 6s1 Valence electrons-2 Discoverer- Julius C Scaliger he found in mines between Panama and Mexico and wrote that no fire or any Spanish art could melt it. In 1557. How its mined- is mined in a similar way to gold and is found in only a few places worldwide, including South Africa, Russia, and Canada. Currently, South Africa produces the largest amount of platinum with roughly 80%. Russia is second in line, but due to platinum’s rarity, only a small amount comes from that area. Platinum is usually found uncombined, and it isstimated that the total amount of mined platinum could not even fill a swimming pool.

Physical and Chemical properties- chemical properties- when it is exposed to air it does not corrode or tarnish. It dose not dissolve easily but when it does it dissolves in aqua regia.It can also dissolve in very hot alkalis Physical- silver grayish metal, it is malleable and ductile, platinum can be hammered into fine sheets of 100 atoms. Chemical Products that are common- when enacted with fluorine gas it will form a volatile(VI)fluoride. Another chemical reaction is tetrachloride (PtCl2). Uses- It is used for jewelry and is very valuable in mechanical applications. Cost- Platinum is $1578.00 per oz. Cool facts- Platinum is worth more than gold. It is not flammable but is able to be melted.Also Its name came from Spain (platina del Pinto) which means little silver in the Pinto river. Ores- Platinum is most commonly found inbetween minerals.
