Fermium is a transuranium element with atomic number 100. Its atomic mass is 257.0951 and its chemical symbol is Fm. All isotopes of fermium are radioactive, with fermium-257 having the longest half life, 20.1 hours. Thus far, too little fermium has...

Fermium is an actinide series transuranium element denoted by the atomic symbol Fm. Its atomic number is 100 and the atomic weight of its most stable isotope is 257. Fermium is a radioactive element which has sixteen known isotopes. It is named for...

Fermium (pronounced /ˈfɝmiəm/) is a synthetic element with the symbol Fm and atomic number 100. A highly radioactive metallic transuranic element of the actinide series, fermium is made by bombarding plutonium with neutrons and is named after nuclear...

Scientists have for the first time literally shed light on properties of the radioactive element fermium--a metal discovered some 50 years ago. Spectroscopy, or the measurement of the wavelengths of light that materials emit or absorb, is a standard way to probe...

When studying physics, Enrico Fermi was in his element.So much so, he has an element named after him.That would be fermium, the 100th element, called that in his honor by admiring colleagues.He is the namesake of the Fermi Institute on the campus of the University...
