Question

why is mass of nucleus always less then sum of its constituents????

Answer 1

Answer: The nucleons expend the energy required for this activity at the expense of their masses, resulting in the nucleus having less mass than its parts combined.

Explanation:

• During the formation of a nucleus, protons and neutrons reach a distance of 10⁻¹⁴m.
• Nucleons are made up of protons and neutrons together.
• The energy necessary for this process is spent at the price of the nucleons' masses.
• As a result, the mass of the discovered nucleus is smaller than the sum of the masses of the individual nucleons.
