The difference between the mass of the nucleus and the mass of the nucleons it contains is converted into ? that holds the nucleus together
photoelectric energy
binding energy

Binding energy

Explanation:

The energy required to bind the nucleus is called binding energy.

Binding energy is equal to the product of mass defect and square of velocity of light.

Mass defect is the difference of mass of neucleons and the mass of atom.

conduction, convection, radiation

it is a negative acceleration
