Mendelevium, including Technical Data, Safety Data and its high purity propertiesresearch, applications and other useful facts are discussed below. Scientific facts such as the atomic structure,ionization energyabundance on Earthconductivity and thermal properties are included. 

Mendelevium is a Block F, Group 3, Period 7 element. The number of electrons in each of Mendelevium‘s shells is 2, 8, 18, 32, 31, 8, 2 and its electronic configuration is [Rn] 5f13 7s2. In its elemental form mendelevium‘s CAS number is 7440-11-1. The mendelevium atom has a radius of and it‘s Van der Waals radius is Mendelevium is radioactive and therefore considered harmful. 

Mendelevium was discovered by Albert Ghiorso, Bernard G. Harvey, Gregory R. Choppin, Stanley G. Thompson and Glenn T. Seaborg  in 1955. Mendelevium was named after Russian chemist Dmitri Ivanovitch Mendeleyev, who created the periodic table. Mendelevium is a synthetic element that  is usually produced by bombarding einsteinium with alpha particles.

Mendelevium Safety Data. The safety data for mendelevium 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. Mendelevium compounds have no biological role.
