Which atomic number element of the periodic table is named after Alfred Nobel, the inventor of dynamite and the founder of the Nobel Prize?

The correct answer is 102.

Key Points

• Nobelium - 102
  • Nobelium is a synthetic chemical element with the symbol No and the atomic number 102.
  • Until now, twelve isotopes have been identified, with 259 No being the most stable.
  • It is the tenth transuranic element and the penultimate member of the actinide series.
  • It can only be used for scientific research.
  • Nobelium is a highly radioactive metal.

Additional Information

• Fermium - 100
  • Fermium is an actinide series radioactive metal with the atomic number 100.
  • Fermium does not occur naturally and was discovered in the debris of the first hydrogen bomb explosion in 1953.
• Dubnium is a synthetic chemical element with the symbol Db and atomic number 105.
  • Dubnium is highly radioactive: the most stable known isotope, dubnium-268, has a half-life of about 28 hours.
  • Dubnium does not occur naturally on Earth and is produced artificially.
• Hassium (Hs) is an artificially produced element belonging to the transuranium group, atomic number 108.
  • The research team, led by Peter Armbruster, produced an isotope of hassium in a fusion reaction by irradiating lead-208 with ions of iron-58.
