Platinum is a silvery-white metal which is resistant to corrosion. Native platinum generally contains up to 80% of the metal, and includes other platinum group metals. The Spanish, who found the metal in small quantities, or as small granules, gave it the name platina, the dimunitive form of silver.

Around the year 1800 accompanying platinum group metals within native platinum were identified. S. Tennant (1761-1815) discovered iridium and osmium.
