![]() ![]() ![]() As you know, fission breaks heavy atom into two or smaller ones whereas fusion brings two or more small atoms together for creating one large atom. Similarly, every star makes use of it for producing energy. On the other hand, fusion happens when two or smaller atoms blend together and make a larger and heavier atom.įurther, fission does not occur naturally whereas the universe is filled with instances of fusion reactions. One is nuclear fission, where an atom splits into two or smaller, lighter atoms. Difference Between Nuclear Fission and Nuclear Fusionīasically, there are two major nuclear reactions which happen for releasing energy because of the presence of high-powered atomic bonds between particles present within a nucleus. Approximately 600 million tons of hydrogen convert into Helium every second in the sun. This temperature together with incredibly high pressure, two isotopes of Hydrogen, Deuterium, and Tritium combine for forming Helium and releases the enormous amount of energy in the form of heat. The temperature at the sun’s core is approximately 15 million degrees Celsius. The pressure at the core of any star is immensely high and that is where the nuclear fusion reaction occurs. It is because of this process that they create such an astonishing amount of heat and energy. If you look at it closely, you will understand that every star in the universe, as well as the sun, is alive because of nuclear fusion. Moreover, both nuclear fusion and fission generate a substantial amount of energy. Further, it is the opposite of nuclear fission reaction as in there, heavy elements diffuse and create lighter elements. This reaction occurs with elements which have a low atomic number, like hydrogen. Nuclear fusion refers to a reaction through which two or more light nuclei collide into each other for forming a heavier nucleus. 2 FAQ on Nuclear Fusion Introduction to Nuclear Fusion ![]()
