Questions and Answers

What is a synthetic element?

  • An element that does not occur naturally on Earth and is created by human manipulation of fundamental particles (correct)
  • An element that has a stable half-life
  • An element that is found in nature in trace quantities
  • An element that occurs naturally on Earth and is stable

    • How are synthetic elements created?

  • By combining two stable elements in a nuclear reactor
  • By cooling down natural elements to extreme temperatures
  • By forcing additional protons into the nucleus of an element with an atomic number lower than 95 (correct)
  • By extracting them from meteorites

    • What is the range of atomic numbers for synthetic elements?

  • 50–75
  • 95–118 (correct)
  • 1–24
  • 120–150
