The platinum group metals (or PGMs) is the name given to the metals from the groups 8, 9 and 10, periods 5 and 6 of the periodic table.
Other names used are platinum group, platinum metals, platinum family, platinoids, platinides, platidises, or platinum-group elements (PGEs).
The metals are:
All these metals have similar chemical properties and tend to occur together in the same mineral. Their physical properties differ slightly, such as density (the metals from the period 6 are almost twice as dense as those from the period 5), and while all are silvery-white in color, osmium tends to have a blueish cast.
