The mass defect is the result of what action occurring?
A. Mass being converted to energy when protons and neutrons bind together in a nucleus
B. Protons and electrons being attracted to each other
C. Energy being converted into moles of atoms when neutrons break apart protons
D. Mass being converted to energy when protons and neutrons break apart in a nucleus
Answer: Option A
Solution(By Examveda Team)
