F see Fluorine; Fe see Iron Fermium (Fm)
Element 100. It is an artificial and radioactive rare-earth element in the actinide series in the Periodic Table. Very little is known about fermium.
Discovery
Fermium was first discovered by Albert Ghiorso and others in 1952
at Los Alamos, New Mexico and the University of California at Berkeley in the radioactive fallout from a nuclear test in the Pacific Ocean.
Technology
Since so little has been isolated, it has no uses.
Geology
It is not found in the environment.
Biology
It is not found in living things.
 Fluorine: Polytetrafluoroethene coatings are found on many household pans to give them their non-stick finish.
The only problem with the material is that it is soft and so can be scratched with metal implements. For this reason, wooden or plastic implements need to be used with non- stick pans.
