List of Platinum Group Metals or PGMs ThoughtCo

Aug 01, 2019 Sources of Platinum Group Metals . Platinum gets its name from platina, meaning "little silver," because the Spaniards considered it an unwanted impurity in silver mining operations in Colombia.For the most part, PGMs are found together in ores. Ultramafic and mafic igneous rocks contain high levels of platinum group metals, the granites contain a low percentage of the metals.

Noble gas Wikipedia

Pierre Janssen and Joseph Norman Lockyer had discovered a new element on August 18, 1868 while looking at the chromosphere of the Sun, and named it helium after the Greek word for the Sun, ἥλιος (hḗlios). No chemical analysis was possible at the time, but helium was later found to be a noble gas. Before them, in 1784, the English chemist and physicist Henry Cavendish had discovered
