francium (usually uncountable, plural franciums)

1. The chemical element (symbol Fr) with an atomic number of 87. It is an intensely radioactive alkali metal that is not found in nature.
   • 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.

   • 2007, Carl J. Gross, Witold Nazarewicz, Krzysztof P. Rykaczewski, The 4th International Conference on Exotic Nuclei and Atomic Masses, page 180:

     (a) Radons and poloniums are compared, (b) poloniums and astatines are compared and (c) radons and franciums are compared.
