with m is mass (kilograms), c is speed of light (meters/sec. Fusion is found in the Sun producing large amounts of energy. The fusion of four protons to form a helium nucleus, two positrons (and two. Fission splits because of a neutron hits the atom dividing it. Fusing two light nuclei can liberate as much energy as the fission of 235U or 239Pu. Fission is when a atom splits emitting large amounts of energy. To calculate the energy released during mass destruction in both nuclear fission and fusion, we use Einstein’s equation that equates energy and mass: (11.9.1) E m c 2. Fusion is when an atom fuses together making energy. Both fusion and fission involve nuclear reactions that release large amounts of energy that can be used to produce electricity. Nuclear power plants are designed in such a way that they cannot form a supercritical mass of fissionable material and therefore cannot create a nuclear explosion. The mass of an elements nucleus as a whole is less than the total mass of its individual protons and neutrons. Mitosis is cell division that results in two identical daughter cells and is primarily used for growth of an organism.
