Elements Named After People (Element Eponyms)


There are 21 elements named after people (element eponyms), although the International Union of Pure and Applied Chemistry (IUPAC) sometimes considers the connection to a person to be indirect. In other words, sometimes the element name was chosen to honor a place or thing, indirectly connecting it to someone’s name.

Did You Know: Seaborgium was the first element named for a person while he was still alive. The name einsteinium had been proposed while Einstein was still alive, but not approved until after his death.
