Platinum is malleable and ductile and has a high melting point. It does not oxidize in air even at high temperatures and is unaffected by common acids. Platinum dissolves in aqua regia mixture of nitric acid and hydrochloric acid in the ratio 1: It is also corroded by halogens, cyanides, sulfur, and caustic alkalis.

Platinum was first discovered by Spanish Conquistadors in Southern America in the 16th century while searching for gold, while first written record of "an unknown noble metal found between Darien and Mexico" dates from from the writings of Italian humanist Julius Caesar Scaliger. However, platinum was already known and used by pre-Columbian Native Americans, while the modern knowledge of platinum dates from about when Spanish general, explorer, astronomer and first Spanish governor of Louisiana Antonio de Ulloa reported over existence of platinum while he was on the French Geodesic Mission to Peru.
Although Ulloa is accredited the discovery of platinum he did not continue with research of the new metal. However, platinum soon attracted attention of numerous European chemists such as Charles Wood, Torbern Bergman, William Lewis and many others, while Henric Scheffer published a detailed description of platinum in describing it as "white gold".
Despite that platinum was for a long period regarded as undesired impurity in silver by the Spanish who were mining silver. Due its rarity and greater difficulty to work with it platinum was used only in a limited way in jewelry by the end of the 19th century.
However, that changed after the development of method for processing platinum ore by English chemist and physicist William Hyde Wollaston in The first writings describing Platinum were in by Italian Julius Caesar Scaliger (not as listed in many places online).
The new metal was further observed during an expedition of New Grenada (now known as Colombia) by Antonio de Ulloa and Don Jorge Juan y Santacilia in The Russian scientist Anatoly Fomenko has claimed Scaliger, Dionysius Petavius and others of having created a false world history.
