The correct answer is option 3 i.e. Mendelevium.

  • The metallic radioactive transuranic element with atomic number 101 in the actinide series, discovered in 1955, is named Mendelevium. Mendelevium is a synthetic element, meaning it does not occur naturally and must be produced artificially through nuclear reactions.
  • It was first synthesized by a team of scientists led by Albert Ghiorso at the Lawrence Berkeley National Laboratory in California, United States.
  • Mendelevium is named after Dmitri Mendeleev, the Russian chemist who is best known for developing the periodic table of elements.
