Palladium, together with rhodium, ruthenium, osmium, iridium, and platinum form a group of elements referred to as the platinum group metals (PGM).Palladium is a lustrous silver-white metal.
Palladium, ruthenium, rhodium, osmium, indium, and platinum make up the platinum group of metals. These consist of layers of palladium sandwiched between layers of ceramic.Finely divided palladium is a good catalyst and is used for hydrogenation and dehydrogenation reactions.
