Platinum is an extremely unreactive (it is found in its native state) chemical element. It is a catalyst for several reactions (such as the hydrogen half-cell), and is used in catalytic converters and in the synthesis of nitric acid. The element was first recognized in 1751, although it was used by the Incas before the Spanish arrived in South America.[1]
