Nuclear Fission Versus Nuclear Fusion ThoughtCo
Jul 11, 2019#0183;#32;Nuclear Fusion . Nuclear fusion is a process in which atomic nuclei are fused together to form heavier nuclei. Extremely high temperatures (on the order of x 10 7 #176;C) can force nuclei together so the strong nuclear force can bond them. Large amounts of energy are released when fusion occurs. It may seem counterintuitive that energy is released both when atoms split and when they merge.
