Chemical Name: Palladium
Chemical Formula: Pd
An element belonging to the platinum group of metals, palladium is steel-white in color, except in powder form, when it appears black. Palladium resists tarnishing in air and, if annealed, it is soft and ductile. Palladium has the lowest density and melting point of the palladium metals and is the most reactive. At room temperature, palladium absorbs up to 900 times its own volume of hydrogen.
