If two deuterium nuclei merge to become helium, 2.2 Me V 2.2 Me V of binding energy are replaced by helium-4’s average binding energy of 7.1 Me V per nucleon, or a total of 4 x 7.1 Me V. Fission (as well as fusion) can be sustained only if energy is released to drive more fission (or fusion). It is also the energy required to break (unbind) a nucleus into separate protons and neutrons.The closer the mass of a nucleus is to the mass of an iron or nickel nucleus (60 AMU), the more binding energy that nucleus has per nucleon.

(For example, when the atomic bomb was dropped on Hiroshima, only about 700 milligrams of mass—about one-third the mass of a U. dime—was converted to energy.) Nuclear energy is usually released as kinetic energy.

The high velocity fragments generate heat as they slow down during multiple collisions.

To see why A carbon-12 atom’s mass is exactly 12.000000 AMU—by definition.

In building a carbon-12 atom from 6 protons, 6 neutrons, and 6 electrons: Loss of Mass (m) = 12.098940 - 12.000000 = 0.098940 AMU Gain of Binding Energy (E) = 0.098940 AMU c Figure 201: Binding Energy.

Let’s say that a very heavy nucleus, such as a uranium nucleus weighing 235.0 AMU, splits (fissions) into two nuclei weighing 100.0 AMU and 133.9 AMU and a neutron (1.0 AMU).

The 0.1 AMU of lost mass is converted to energy, according to Einstein’s famous equation, is huge.

, a type of decay, is beta decay in reverse; that is, an atom’s electron enters the nucleus, combines with a proton, and converts it into a neutron.

Few scientists realize that on rare occasions heavy nuclei will decay by emitting a carbon-14 nucleus ( This calls into question the basic assumptions of the radiocarbon dating technique, especially when one understands the origin of earth’s radioactivity. " on pages 524–528.] Only about 65 naturally occurring radioisotopes are known.

Evolutionists say earth’s radioactive material evolved in stars and their exploded debris.
