# What element is/used to be called Fb? [closed]

What element used to be called Fb? It was supposedly found in a meteorite in Antarctica and I can't find any references of it.

• To my knowledge, there is no element with the symbol Fb. There are however, some with b as the second letter of the element symbol, such as Rb, Pb, Sb, Tb, and Yb. – Klaus-Dieter Warzecha Jan 20 '17 at 6:56
• I'm guessing a P looked like an F somewhere and that it contains lead...wild guess. Any idea at all of where you saw the reference? On-line, text book, sci-fi channel ;) – airhuff Jan 20 '17 at 7:02

• @Secret that's very reassuring. Thanks for digging it up. – Martin - マーチン Jan 20 '17 at 8:15
• Its a text-question in a book. Everything is made up... Its an exercise – Fl.pf. Jan 20 '17 at 10:15

Given that Facebookium ($\ce{Fb}$) does not exist, it is most likely a typo/transfer error for the first character of the element symbol.
The possible choices are $\ce{Rb}$, $\ce{Pb}$, $\ce{Sb}$, $\ce{Tb}$, and $\ce{Yb}$.
Among these, lead ($\ce{Pb}$) is very likely to be the right one.
