The Element Palladium


Palladium is one of the rarest metals on Earth and belongs to the Platinum group. Amazingly, when Palladium is kept under room temperature and normal atmospheric pressure, it can absorb up to 900 times its own volume of hydrogen which makes Palladium a safe storage medium for Hydrogen. Palladium is widely used for making electrical devices such as computers, mobile phones, LCD televisions etc.

Dentistry, watch making, air craft parts, surgical instrument manufacturing, and electrical contacts manufacturing are some of the other applications of Palladium. Since this element is rare and precious, it is also used in jewelry. Palladium is also used in printing photographs as well.
