PHONETICS

IDENTIFICATION

Platinum is a dense, malleable, ductile, highly unreactive, precious, grey-white transition metal. It has six naturally occurring isotopes and is one of the rarer elements in the Earth’s crust with an average abundance of approximately 5 μg/kg. It occurs in some nickel and copper ores and due to its scarcity in the Earth’s crust, only a few hundred tonnes are produced annually.
