Question 2

When a neutron and proton combine to form a deuteron, a 2.2 million electron volt gamma ray is emitted. What does this indicate about the binding energy of the deuterium nucleus?
a. Its binding energy is negative, i.e., it is unstable.
b. It has a small binding energy.
c. Its binding energy is about 2.2 million electron volts.
d. The deuterium nucleus is slightly more massive than the sum of the proton and neutron masses, because of energy mass equivalence.
e. The deuterium nucleus contains 2.2 million electron volts more energy than the separated neutron and proton.
