Nuclear Fusion

The binding energy per nucleon curve (Figure 43.1) peaks at a nucleon number of about 56. This means that nuclei having A = 56 are more tightly bound than either less massive or more massive nuclei. Nuclear fission of nuclei with A ≈ 240 releases energy because the fragments have mass numbers closer to the A = 56 peak and are therefore more tightly bound. Nuclear reactions between light nuclei that produce more massive and more tightly bound nuclei also release energy. 

what are the two models

explanation:

a plasma is a warm ionized gasoline consisting of approximately equal numbers of definitely charged ions and negatively charged electrons. the characteristics of plasmas are notably unique from the ones of ordinary neutral gases in order that plasmas are considered a awesome "fourth kingdom of remember."
