Radioisotope: an unstable isotope that spontaneously changes its nuclear structure and releases energy in the form of radiation. Isotopes Stable Radioisotopes.
Nuclear Fission Nuclear Fission is when a large nucleus splits into two smaller nuclei, releasing neutrons and energy –Heavier nuclei tend to be more.
For each atom, in its natural state, the number of electrons and the number of protons is equal. This number may or may not be the same as the number.
