Nuclear Chemistry Part 1

Nuclear Chemistry Part 2


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.

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.
