Tuuma energia
had been just recently discovered at the time 1895. It is energy released by the splitting (fission) or
merging together (fusion) of the nuclei of atoms. The conversion of nuclear mass to energy is
consistent with the mass-energy equivalence formula E = m.c², in which E = energy release,
m = mass defect, and c = the speed of light in a vacuum.
Nuclear chemistry can be used as a form of alchemy to turn lead into gold or change any atom to
any other atom (albeit through many steps). Radionuclide (radioisotope) production often involves
irradiation of another isotope (or more precisely a nuclide), with alpha particles, beta particles, or
gamma rays. Iron has the highest binding energy per nucleon of any atom. If an atom of lower
average binding energy is changed into an atom of higher average binding energy, energy is given
off.
What is nuclear fusion?
Nuclear fusion is the process by which multiple like-
charged atomic nuclei join together to form a heavier
nucleus
