   • 2003, Bill Bryson, A Short History of Nearly Everything, BCA, page 221:

     The most elusive element of all, however, appears to be francium, which is so rare that it is thought that our entire planet may contain, at any given moment, fewer than twenty francium atoms.

2. (countable) A single atom of this element.
   • 1999, Peter J. Krieger, Understanding Chemical Principles: A Learning Companion, page 56:

     Notice that franciums are balanced without even thinking in moles, atoms, or whatever.
