element)
Nobelium is a Block F, Group 3, Period 7 element. The number of electrons in each of Nobelium‘s shells is 2, 8, 18, 32, 32, 8, 2 and its electronic configuration is [Rn] 5f14 7s2. In its elemental form nobelium‘s CAS number is 10028-14-5. The nobelium atom has a radius of -.pm and it‘s Van der Waals radius is 200.pm. Nobelium is radioactive. The appearance of Nobelium is unknown.

Nobelium was discovered by Nobel Institute of Physics in Stockholm and later by Albert Ghiorso, Torbjorn Sikkeland, J. R. Walton and Glenn T. Seaborg  in 1958. The element was named in honor of Alfred Nobel. 



Nobelium Safety Data. The safety data for nobelium metalnanoparticles and its compounds can vary widely depending on the form. For potential hazard information, toxicity, and road, sea and air transportation limitations, such as DOT Hazard Class, DOT Number, EU Number, NFPA Health rating and RTECS Class, please see the specific material or compound referenced in the left margin. Nobelium compounds have no biological role.
