Nuclear energy ~8% of U.S energy from nuclear power plants
Background image of page 2
Burning of fossil fuels changes bonds between electrons so elements retain their identities Nuclear reactions change forces that hold nuclei together - these forces are ~ a million times greater Nuclear fusion  – joining of two very light elements to make a heavier element  Nuclear fission  –breakdown of large nuclei to form two smaller nuclei * Both processes create energy because a small amount of mass is converted to energy when you create a nucleus
