Chemical elements, particularly synthetic ones discovered after around 1940, are occasionally named after individuals. However, it is rare for elements to be named after their discoverers, and only two have been named after individuals who were alive at the time of the naming. Do you know which?
Who is the first person to have an element named after them in their lifetime?
See answer
Glenn T. Seaborg: Element 106 – Seaborgium (Sg)
The element was first given the systematic name Unnilhexium (ordinal number 106). It was synthesized in September 1974 by a team led by Albert Ghiorso (1950–2010) and Glenn T. Seaborg (1912–1999) by bombarding Californium-249 with oxygen-18 nuclei [1,2]. They reported the isotope with mass number 263.
A team led by Georgi N. Fljorov (1913–1990) and Yuri Z. Organesjan (1933) obtained the isotope of element 106 with mass number 261 in June 1974 by bombarding lead-208 with chrome-54 nuclei.
The final name was given by IUPAC in 1997. It was controversial because Seaborg was still alive at the time.
And who is the second?
See answer
After Glenn T. Seaborg with seaborgium, Yuri Oganessian is only the second living scientist to have an element named after him: Element 118 – Oganesson (Og) [3]. It was officially named on November 28, 2016.
