Fission and Fusion Flashcards
Nuclear Binding Energy
Energy required to hold the nucleus together
Mass of protons and neutrons- mass of nucleus= mass defect
Nuclear Fission
Heavy, unstable nuclei being split into lighter, more stable daughter nuclei by the absorption of a slow moving neutron
Releases energy
How to you calculate the energy released from fission?
Mass of reactants- mass of products
x c2
Nuclear Fusion
Light nuclei fusing together under the right conditions to form heavier nuclei
Releases energy
Why is fusion still a challenge?
Extreme temperatures needed
Difficult to contain
Why are extreme temperatures needed for fusion?
So strong nuclear force can overcome electrostatic repulsion between nuclei
Nuclei must be forced close together
