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.
Your answer is correct, I do not understand why it would be wrong. The electron accepting tendency of an atom is known as the tendency of an atom to accept an electron. This is ranked on a scale of 0.7 to 3.98 and these species have the following values: F: 3.98 O: 3.44 C: 2.55 Be: 1.57 Li: 0.98
