| | Density of Platinum |
 | | The platinum family metals, consisting of ruthenium, rhodium, palladium, osmium, iridium, and platinum, are transition metals characteristically known for their strong interatomic bonds and high density. |
 | | The character and strength of these bonds are what determine the crystalline structure and physical properties platinum is most known for-malleable, ductile, corrosion-resistant, high boiling and melting points, stable electrical properties, does not oxidize in air at any temperature, and is insoluble in hydrochloric and nitric acid. |
 | | However, platinum is often found with small quantities of other platinum family metals in deposits in Columbia, Ontario, the Ural Mountains, and in certain western US states. |
