The chemical element nobelium, atomic number 102 on the periodic table of elements, is a rare and man-made metal first discovered in 1958 by a team led by Glenn T. Seaborg at the University of California, Berkeley. It is named after the Swedish chemist and industrialist Alfred Nobel, who is also the namesake of the Nobel Prizes.
Nobelium is a shiny silver metal that is characterized by high levels of radioactivity and, in its stable form, occurs in very small amounts at most. It has no known natural occurrences and is usually produced by certain nuclear reactions in nuclear power plants. Because of its rarity and its radioactive properties, nobelium is of no practical use.
Abbreviated form: [Rn] 5f14 7s2 .
The following table lists the ionization energies IE (ionization potentials); the IE is the energy required in electron volts (eV) per atom to separate a given electron from an Nobelium atom.
An overview of the nuclides as well as the isotopic data and properties are listed on the following page: Nobelium isotopes.
