Nuclear fission is a radioactive process involving the splitting of a large unstable nucleus into smaller/lighter nuclei with the release of large amount of energy. The large amount of energy is achieved by bombarding fast moving neutron against the the unstable nucleus of the large substance/elements undergoing fission. The resulting energy (produced from the fission) is used in nuclear reactors to heat water (to produce electricity), which can also cause a turbine to convert its kinetic energy into mechanical energy.
I believe the correct answer from the choices listed above is option C. The type of substances that has <span>chemical bonds that are not directional and valence electrons that move freely between the atoms are metals. Hope this answers the question. Have a nice day.</span>
