Fission and Fusion are both nuclear reactions that involve the particles in the nucleus of an atom.

N UCLEAR E NERGY Fusion and Fission Notes and Diagrams

N UCLEAR E NERGY Nuclear energy is energy that is stored in the nucleus or center core of an atom. The nucleus of an atom is made of tiny particles of protons (+ positive charge) and neutrons (no charge). The electrons (- negative charge) move around the nucleus. Nuclear energy is the force that holds the nucleus together in an atom.

T WO TYPES OF NUCLEAR ENERGY Split atomsFuse atoms FissionFusion

FISSION Fission is a way of splitting an atom into two smaller atoms. The two smaller atoms don't need as much energy to hold them together as the larger atom, so the extra energy is released as heat and radiation.

F ISSION N UCLEAR P OWER P LANTS AND N UCLEAR BOMBS

FUSION Fusion is a way of combining atoms to make a new atom. Hydrogen atoms are combined to make helium. Helium doesn't need that much energy to hold it together, so the extra energy produced is released as heat and light.
