Question

Which best explains why nuclear reactions release more energy than chemical reactions?

The forces holding the nucleus together are much stronger than the forces binding electrons to atoms.

Protons have a much higher mass than either neutrons or electrons.

During a chemical reaction, some of the mass of the reactants is converted to energy.

In nuclear reactions, the electrons in the atom are not involved in the transmutation.

Answer 1

Protons have a much higher mass than either neutrons or electrons.
