What are the platinum group metals?

Answer 1

The platinum group metals (abbreviated as the PGMs; alternatively, the platinoids, platidises, platinum group, platinum metals, platinum family or platinum group elements (PGEs)) is a term used sometimes to collectively refer to six metallic elements clustered together in the Periodic Table. These elements are all transition metals, lying in the d-block (groups 8, 9, and 10, periods 5 and 6).

The six platinum group metals are ruthenium, rhodium, palladium, osmium, iridium, and platinum. They have similar physical and chemical properties, and tend to occur together in the same mineral deposits
