Sum of the masses of constituent nucleons as compared to the mass of the resultant nucleus is?
Answer: Smaller
Explanation
The mass of a nucleus is always less than the sum of the masses of its constituent nucleons.
This difference in mass is known as the "mass defect".
When nucleons come together to form a nucleus, they release energy in the form of binding energy.
According to Einstein's famous equation E=mc², this energy released corresponds to a decrease in mass.
