When two protons and two neutrons combine to form ⁴He, the helium nucleus is less massive than the sum of the four original particles used to construct it. What is the significance of this result?

Question

Quizplus · Accepted Answer

The lost mass is transformed into energy according to the principle of mass-energy equivalence, as described by Einstein's equation E=mc^2. This principle explains that the mass defect (the difference in mass) is converted into binding energy, which holds the nucleus together.
