fission the process whereby certain heavy nuclei (e.g.,23592U) break apart
into two approximately equal smaller, more stable, nuclei called
“daughters.” Fission is usually initiated by bombarding heavy nuclei
with slow moving neutrons. In the process, additional neutrons are
released, which can cause the fission of yet more nuclei, thus sustaining
a chain reaction. Fission processes release large quantities of energy.fusion the process in which two small nuclei (usually H or He) combine to
form a larger, more stable, nucleus. The heat and light of the sun are
generated by the fusion of hydrogen isotopes to form helium nuclei.gamma rays (g) high energy electromagnetic radiation. The wavelength of
gamma rays is approximately 10–12 m (refer to a standard chemistry
