Question

The difference between the rest mass of the nucleus and the sum of the masses of the nucleons composing a nucleus is known as:

• A. Binding energy
• B. Mass defect
• C. Nuclear energy
• D. Isotopic mass

Hint:

The mass defect is the difference between the mass of a nucleus and the sum of its individual nucleons, and it is related to the binding energy of the nucleus.

Answer 1

The Correct Option is B

Step 1: Understanding mass defect. The mass defect is the difference between the total mass of the separate nucleons and the actual mass of the nucleus. It represents the energy required to separate the nucleus into individual nucleons.
Step 2: Conclusion. Thus, the difference is known as the mass defect.
