Platinum is a chemical element, typically found as a solid in its elemental form. It has the chemical symbol Pt, atomic number (number of protons) Z = 78, and a standard atomic weight of 195.078 grams per mole.
Platinum is considered a member of the "Transition metal" class of elements. At a pressure of 101.325 kPa, it has a boiling point of 3,825 °C and a melting point of 1,768.4 °C. Platinum is also considered a precious metal and is used as a catalyst in many chemical reactions.
