Overview

Nobelium (No) is a synthetic chemical element with atomic number 102. It is named in honor of Alfred Nobel. This radioactive metal was first reported by a team of scientists working at the Nobel Institute of Physics in Stockholm in 1957. It is classified as an actinide and is not found naturally on earth.

Characteristics

• Atomic number: 102
• Electron configuration: [Rn] 5f^14 7s^2
• Physical properties:
  • Phase at standard temperature and pressure: Solid (predicted)
  • Melting point: 1100 K (800 °C, 1500 °F) (predicted)
  • Density: 9.9(4) g/cm^3 (predicted)
• Atomic properties:
  • Oxidation states: +2, +3
  • Electronegativity: 1.3 (predicted)
  • Ionization energies: Not yet refined due to scarcity and high radioactivity
• Crystal structure: Face-centered cubic (predicted)
• CAS number: 10028-14-5

History and Discovery

• Nobelium was discovered at the Joint Institute for Nuclear Research in 1965.
• Since the initial report, numerous experiments have confirmed its existence and synthesized several isotopes, with nobelium-259 being the most stable.
• It has been shown to exhibit chemical properties similar to those of ytterbium in the periodic table, with a more stable +2 oxidation state than the +3 state in aqueous solution.
