Start Quiz
1.
Near which mass number does the binding energy per nucleon curve peak?
A ≈ 4
A ≈ 120
A ≈ 238
A ≈ 56
2.
Why does fusion of light nuclei release energy?
Products have lower binding energy per nucleon
Products have higher binding energy per nucleon
Neutrons are created
Electric repulsion is zero
3.
The rise in the curve for small A is due to...
Electrostatic repulsion
Gravity
Increasing number of nearest neighbours attracted by the strong force
The weak force
4.
Which has the highest binding energy per nucleon?
Iron-56
Hydrogen-2
Helium-4
Uranium-238
5.
Energy released in fission arises because...
fragments are lighter in nucleons
fragments have higher binding energy per nucleon than the original nucleus
protons turn into neutrons
electrons are released
6.
Why does the curve fall for large A?
Neutrons decay
Strong force is unlimited in range
Electrons are added
Long-range proton repulsion grows faster than the strong-force attraction
