Nuclear Fission vs. Nuclear Fusion


Nuclear fusion is a process in which energy is released when atoms combine to form a new, larger atom. The nuclei of the two atoms join together to form a heavier nucleus and to produce large amounts of energy. Fusion reactions can only occur at very high temperatures that are only possible in the sun and stars. Fusion in the space creates light and heat that helps warm the Earth and help life live. It is used to create hydrogen bombs because the amount of energy released can produce large explosions. (Energyquest, 2009)

Nuclear fission is a process in which atoms are broken apart to create smaller atoms. This also creates a large sum of energy that can produce electricity. In nuclear fission the nuclei of the two atoms are split apart into two smaller atoms with less mass. Fission is used to create atom bombs and nuclear bombs because it has a chain reaction and if used correctly can create huge explosions. (Energyquest, 2009)

  1. sort these isotopes by whether they are most likely to undergo fusion or fission.
    (a) 3He
    (b) 14C
    (c)  1 1H
    (d) uranium-235
    (e) polonium-239
    (f)   nitrogen-14
