The only lanthanide that does not occur in nature, FTP, what is this element whose name is derived from a famed mythological captive?
Attempts to isolate this element prior to its real discovery in 1947 at Oak Ridge led to the announcement of the elements illinium and florentium. Its isotope with mass 147 can be separated from other rare-earth isotopes via an ion exchange technique. Sandwiching this element between layers of silicon produce a miniature battery that can operate continuously in extreme temperature conditions for up to five years.
