Quiz

23.1.3 Mass Defect and Binding Energy – Check yourself

Submit quiz
Once you submit, you will no longer be able to change your answers. Are you sure you want to submit the quiz?
1.
The mass defect of a nucleus is
mass of nucleus minus mass of separate nucleons
zero for stable nuclei
mass of protons only
mass of separate nucleons minus mass of nucleus
2.
A nucleus has mass defect 0.050 u. Its binding energy is closest to
4.7 MeV
46.6 MeV
0.05 MeV
931.5 MeV
3.
Which nucleus lies near the peak of the binding energy per nucleon curve?
Hydrogen-2
Uranium-238
Iron-56
Helium-3
4.
Nucleus X has total binding energy 800 MeV and A = 100. Its binding energy per nucleon is
8 MeV
0.125 MeV
80 MeV
80 000 MeV
5.
Fission releases energy because
the products have lower binding energy per nucleon
the products have higher binding energy per nucleon
neutrons are created
the products have more mass
6.
On the curve, the binding energy per nucleon for very light nuclei compared with helium-4 is
much higher
about the same
negative
lower, with helium-4 a local peak
