Was technecium "recently" renamed technetium in English? I know when I formally studied chemistry (in the USA) that earth, air, water and fire were on the periodic table, but I really remember the element as being technecium.


After German chemists claimed to have discovered element 43 in 1925, the name masurium was used in the first publications. However, the German experiments could not be reproduced.

The official discovery of element 43 was accomplished by C. Perrier and E. Segrè in 1936. They proposed the name technetium (see Perrier, C.; Segrè, E. Technetium : The Element of Atomic Number 43, Nature, 1947, 159, 24.).

In 1949, the 15th IUPAC Conference adopted this name.

The name technetium was also used in the early American literature, for example in Radioactivity Applied to Chemistry; Wahl, A. C., Bonner, N. A., Eds.; John Wiley & Sons: New York, 1951.

  • $\begingroup$ LOL - That "early American literature" was what I cut my teeth on. My first high school chemistry class was in 1967. $\endgroup$ – MaxW Sep 15 '16 at 17:39

It's always been technetium in English.

In fact, I can't find an English entry for technecium on the internet at all. I'd venture to guess you're Czech based on the search results, which did yield other language pages.

  • $\begingroup$ Here is a black swan, one of many actually... books.google.com/… $\endgroup$ – MaxW Sep 15 '16 at 17:35
