Nuclear Fission and Fusion I can draw a model of nuclear fission. I can recognize a nuclear fission equation. I can describe two applications for nuclear fission. I can draw a model of nuclear fusion. I can recognize a nuclear fusion equation.

I can draw a model of nuclear fission. I can recognize a fission equation. • Induced fission- a neutron is absorbed by a heavy isotope, and it splits into two particles of uneven mass plus 2 or 3 neutrons and energy. The amount of energy released is called binding energy- energy required to keep the nucleus together.

I can describe 2 applications of nuclear fission. • Applications of fission – Nuclear power-fission is controlled, and nuclear energy released is transformed into electrical energy

Fat Man and Little Boy • Nuclear Weapons- fission releases neutrons that cause a chain reaction and huge release of energy (BOOM) when not controlled.

I can draw a model of nuclear fusion. I can recognize a fusion equation. • Fusion- the combination (or fusing) of two lighter nuclei into one larger nuclei It requires a HUGE amount of energy to overcome the repulsion between the positively charged protons. It requires heat (108 K or 179, 999, 540. 33 F) to cause fusion to occur. Fusion is what causes the energy from the sun and stars. Fusion releases much more energy than fission!!
