Fermium is a synthetic, radioactive metallic element. It has the symbol Fm and atomic number 100. It is an element in the actinide series. It is named after nuclear physicist Enrico Fermi. Fermium became the eighth transuranic (having an atomic number greater than 92) element discovered. It was first discovered in 1952 by a team of scientists led by Albert Ghiorso. They found fermium-255 in debris of the first hydrogen bomb explosion from Operation Ivy. Fermium-255 was created when...
