Question
The difference between the expected mass (sum of the masses of individual protons, neutrons, and electrons) and the actual measured mass of an isotope is called:
Answer: B
💡 Solution & Explanation
Mass defect ($\Delta m$) is defined strictly as the difference between the expected theoretical mass of a nucleus and its actual measured isotopic mass. This missing mass is converted into binding energy.
