  1. All About Platinum!!! By: Tristen White

  2. Periodic Table Information. • Platinum (Plat-n-uh-m). • Atomic symbol: Pt • Atomic mass: 195.08 • Group #: 10 • Period #: 6

  3. Here is a good example of platinum.

  4. 2-D Model of platinum’s atom.

  5. Physical Properties • Platinum’s physical properties include: • A melting point of 2041.4 K (or 3214.9°F). • A boiling point of 4098 K (or 6917°F). • A density of 21.45 g/cm3. • Platinum's state of matter is a solid. • Platinum is malleable. • Platinum is also ductile. • Platinum has a sliverish-white color. • Platinum is shiny. • Platinum conducts both heat and electricity.

  6. Chemical Properties • Platinum doesn’t have very many chemical properties, but here are a few: • Platinum is incompatible with aluminum, acetone, arsenic, ethane, hydrazine, hydrogen peroxide, lithium, phosphorus, selenium, tellurium, and various fluorides. • Platinum doesn’t corrode easily • Platinum also doesn't tarnish. • Platinum can’t rust, either.

  7. Uses One of platinum’s biggest uses is in jewelry, and it is also used to make wire. Besides this, platinum is also used in dentistry, thermocouples, and electrical contacts. It is also used in laboratories to make crucibles and vessels. Lastly, because platinum is highly resistant to corrosion, people use it to protect or preserve items by coating the item in platinum.

  8. History Platinum was discovered by Antonio de Ulloa and Jorge Juan y Santacilia in 1735 in Peru. It was first named platina, which means “little silver” in Spanish. Platinum was recognized as a new element by a Swedish man named Sheffer in the 18th century. In 1784, platinum was used in Berlin to make strong laboratory tools. Platinum had some other industrial uses in the 17th century. Columbia was one of the one of the only biggest producers of platinum in 1820, but stopped exporting it. Then Russia in 1822 began to find platinum in the Ural Mountain gold mines. 18 years later, Russia almost had 500,000 ounces of platinum minted by their government.

  9. Isotopes of Platinum There are a total of 43 known isotopes of Platinum, with 5 of them being stable. These stable ones are 192Pt, 194Pt, 195Pt, 196Pt, and 198Pt.

  10. Other Interesting Facts • Platinum is a very rare element on Earth, but there is a lot of it on the moon and in meteorites. • Platinum is part of the Platinum Group Metals (PGM). • Platinum is more common in the USA, South Africa, and Russia. • The Queen Mother wore a crown made from platinum. • To produce one ounce of platinum, 10 tons of raw mineral are required.
