Light Nuclei Can Be Split

question 119

Multiple Choice

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.
