What are transuranic elements?
✓

Answer

  • The man-made elements heavier titan Uranium (Z = 92) in the Actinoid señes are called transuranic elements.
  • These are synthetically or artificially prepared (man-made) elements starting from Neptunium (Z= 93).
  • Transuranic elements arc generally considered to be from Neptunium (Z = 93) to Lawrencium (Z = 103).
  • Recently elements from atomic number 104 (Rf) to atomic number 118 (Og) or (Uuo) in 6 d series have also been identified as transuranic elements.
  • All transuranic elements are radioactive.
