Fermium is a radioactive metal and one of the actinides which was discovered in the middle of the last century by a group of American scientists, in the labs of the University of California. Its name was given after Enrico Fermi, a prominent scientist and nuclear physicist. The only way to receive this rare element is in terms of nuclear reactors, by processing plutonium. Fermium is extremely toxic and very dangerous to the life on our planet. It has no other applications but research, and every year only a few grams of this chemical element are produced.
