  • Carbon-14 is a well-known example of an unstable atom used in radiometric dating.
  • The nucleus of an unstable atom transforms into a more stable configuration by emitting radiation.
  • Nuclear reactors harness the energy released from billions of unstable atoms splitting apart.
  • Having too many or too few neutrons can make an atom unstable.
  • Scientists predict how long it will take for this particular unstable atom to decay.
  • If an atom is unstable, it is considered radioactive.
