The world needs a new source of energy, an unspillable source.

How can both nuclear fission and nuclear fusion release energy?

Question by smilinchick_21: How can both nuclear fission and nuclear fusion release energy?
Coming from a chemistry point of view, we are familiar with the concept that making bonds requires energy, and breaking bonds releases energy. So, it follows that fusion should require energy, and fission release energy. However, from a nuclear point of view we know that they both release energy.

Anyone care to explain this to me? I have an exam tomorrow!!!!!
The answer has to incorporate:
-Binding energy per nucleon
-Iron being the most stable element because of its binding energy per nucleon
-driving force of nuclear reactors.

Answer by shadycaliber
Look up “National Ignition Facility” it may have some answers for you. It’s breaking bonds to release energy
