The identity of the atom is determined by the # of protons in the nucleus.

The identity of the atom is determined by the # of protons in the nucleus. One can change one kind of atom into another by changing the number of protons in the nucleus These changes involve enormous amounts of energy. This is the source of nuclear energy and the atomic bomb.
