If light nuclei are forced together, they will fuse with a yield of energy because the mass of the combination will be less than the sum of the masses of the individual nuclei. Suppose the combined nuclear mass is less than that of iron at the peak of the\u00a0<strong>binding energy curve. In that case,<\/strong> the nuclear particles will be more tightly bound than they were in the lighter nuclei, and that decrease in mass comes off in the form of energy, according to the Albert Einstein relationship. For elements like uranium and thorium, fission will yield energy. Fusion reactions have an energy density many times greater than\u00a0<a title=\"Nuclear Fission\" href=\"http:\/\/sitepourvtc.com\/nuclear-power\/fission\/\">nuclear fission<\/a>, and fusion reactions are millions of times more energetic than chemical reactions.<\/p>\n<h2>Nuclear Fission vs Fusion &#8211; Reactions<\/h2>\n<div   id="8n9s8rpp6h"     class=\"lgc-column lgc-grid-parent lgc-grid-50 lgc-tablet-grid-50 lgc-mobile-grid-100 lgc-equal-heights \"><div   id="8n9s8rpp6h"     class=\"inside-grid-column\">\n<h2>Uranium &#8211; 235 Fission<\/h2>\n<p><a title=\"Uranium 235\" href=\"http:\/\/sitepourvtc.com\/nuclear-power-plant\/nuclear-fuel\/uranium\/uranium-235\/\">Uranium 235<\/a>\u00a0is a\u00a0<a title=\"Fissile Material\" href=\"http:\/\/sitepourvtc.com\/glossary\/fissile-material\/\">fissile isotope<\/a>,\u00a0and its\u00a0<a title=\"Cross-sections of Uranium\" href=\"http:\/\/sitepourvtc.com\/nuclear-power-plant\/nuclear-fuel\/uranium\/cross-sections-of-uranium\/\">fission cross-section<\/a>\u00a0for thermal neutrons is about\u00a0<strong>585 barns<\/strong> (for 0.0253 eV neutron).
