Platinum 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.
As a pure metal, platinum is silver-white in color, lustrous, ductile, and malleable
Platinum has many uses. It is a great conductor with excellent strength so it can be used in contacts to prevent wearing down.
In the laboratory, platinum wire is used for electrodes; platinum pans and supports are used in thermogravimetric analysis because of the stringent requirements of chemical inertness upon heating to high temperatures (~1000 °C).
