Answer:

Explanation:

This signifies a defect in mass. The phenomenon is known as mass defect. Mass defect is compares the mass of an isotope to that of the nucleons in the nucleus.

The mass defect implies the energy that was given off when the protons and neutrons combine to form the new helium atom. The mass defect helps us to understand why the mass of an atom might not eventually correspond to what we obtain theoretically by calculation.
