Answer:
Light nuclei can be split. For example, a deuteron, which is a proton-neutron
combination, can split into a separate proton and separate neutron. Does such a process
yield energy or cost energy? Why?
A) Yields energy. Splitting nuclei of any sort is a basic example of a nuclear reaction
releasing massive amounts of energy.
B) Neither. The amount of energy required to split the light nuclei is exactly the same as
that released. This is the basis of the Law of Conservation of Energy.
C) Costs energy. This fact is consistent with the sum of the masses of the separated
proton and neutron being greater than the mass of the original deuteron.
D) Yields energy. This fact is consistent with the sum of the masses of the separated
proton and neutron being less than the mass of the original deuteron.
