Nuclear Fission

The breaking up of a larger nucleus into smaller nuclei
The decrease in mass per nucleon, matches the increase in binding energu per nucleon
This binding energy per nucleon is a negative energy and represents energy that is lost (radiated away) during the reaction.
Binding energy per nucleon also represents the energy that would need to be added to liberate a nucleon from the nucleus

Nuclear Fission

Fission & Fusion

Nuclear Fusion

The joining of smaller nuclei into a larger nucleus
The decrease in mass per nucleon, matches the increase in binding energu per nucleon
This binding energy per nucleon is a negative energy and represents energy that is lost (radiated away) during the reaction.
Binding energy per nucleon also represents the energy that would need to be added to liberate a nucleon from the nucleus

Nuclear Fusion

Fusion Energy

Binding Energy per Nucleon

Nuclear Reaction E = mc²

Binding Energy per Nucleon

Binding Energy per Nucleon is a negative energy or a debt of energy. This is the amount of energy it would take to liberate a nucleon from the nucleus. This energy was originally radiated off when the nucleus formed.

The energy radiated off, the Binding energy, is lost energy and comes from mass that is lost by the nucleons. Mass per Nucleon shows what is left over once a bound nucleon has radiated away some of its mass.

Mass per Nucleon

Fission:The breaking up of a larger nucleus into smaller daughter nuclei. Anything above Iron will radiate off energy.

Fusion:
The joining of smaller nuclei into a larger nucleus. Anything below Iron will radiate off energy.
