Andy Brunning of Compound Interest (“Explorations of everyday chemical compounds”) has a great post called A Periodic Table of Rejected Element Names that gives you the background to element names that wound up falling by the wayside; the first is:
Element 4: Glucinium (Beryllium)
The French chemist, Louis Nicolas Vauquelin, examined both emerald and beryl and correctly reported that they contained a new element in 1798. He named this element glucine, with the symbol Gl, but as this name was very similar to that of the amino acid glycine it was criticised. When the first samples of the element were later isolated in 1828, the acceptance of the name beryllium, suggested by another chemist, Martin Henrich Klaproth, became more widespread. However, it wasn’t until 1949 that IUPAC ruled the element should be exclusively called beryllium.
And my two favorites:
Element 94: Extremium (Plutonium)
Extremium was reportedly one of the names considered by US chemists on their discovery of element 94 in 1940. However, the eventually settled on Plutonium (with Seaborg’s little joke of its symbol being Pu instead of Pl) in order to continue the series of planet-based element names.
Element 95: Pandemonium (Americium)
The discovery of elements 95 and 96 in 1945 spurred a host of suggestions for their names. Glenn Seaborg reportedly related that his colleague, Tom Morgan, referred to elements 95 and 96 as pandemonium and delirium. Supposedly, he considered proposing these names to IUPAC’s naming committee. Though a large number of names were suggested, Seaborg eventually plumped for americium for element 95.
If you’re curious about the names actually in use, we covered that in 2004.
