In mediaeval times metals like gold and platinum were called "noble metals" because they "were not subject to corruption", that is, they did not tarnish nor rust.
When William Ramsay and co-workers discovered five group 18 elements at the end of the 19th century, they were known as the "inert gases" because they were unreactive, or as the "noble gases" by analogy with the very unreactive metals. After compounds of xenon were discovered in the 1960s, the former name dropped off, and since then they have been known as the "noble gases"
