How do binding forces in atomic nuclei affect the amount of energy in nuclear fission versus nuclear fusion?

• There is a larger difference in binding forces in nuclear fission.

• There is a larger difference in binding forces in nuclear fusion

• The products have a greater mass than the reactants in fission

• Binding forces do have an effect on nuclear reactions

In nuclear fission, some mass is converted to energy. This causes -

• final mass to be less than initial mass

• final mas to be more than initial mass

• final mass to be equal to initial mass
