Atomic #78 | transition metal
Platinum is an extremely rare metal, sometimes mistaken for silver yet often more expensive than even gold! Platinum occurs on Earth in very small concentrations, but there are large deposits of the element present in the State of Tamil Nadu, India. It exists in very high abundance on the Moon and in meteorites. As a result, the element [Pt] is found even in regions of meteor impact on Earth where it can be mined economically, as is the case with the Sudbury Basin in Ontario, Canada. In ancient times, people in Egypt and the Americas used [Pt] for jewellery and decorative pieces, often mixed with gold. The first recorded reference to [Pt] was in 1557 when Italian physician Julius Scaliger, describing the metal as 'unmeltable'.
