Binding Energy per Nucleon

B_A = E_b / A_n

What it says

How tightly each nucleon is held, which is what makes iron the most stable nucleus.

Symbol	Quantity	Dimension
`B_A`	Binding energy per nucleon (J)	`M L^2 T^-2`
`E_b`	Total binding energy (J)	`M L^2 T^-2`
`A_n`	Nucleon count (dimensionless)	`1`
