Q6 (25): Answer True or False for the following 5 questions.

1. Neutrons and protons alternate filling orbitals by the nuclear Aufbau principle.
2. Paired neutrons in orbitals are more stable than single neutrons in orbitals.
3. The nuclear shell model states that the most stable (most bound) nuclear levels are filled for protons and neutrons, separately, in shells of increasing energy.
4. All stable nuclei are spherical in their ground state ( = 0).

Odd-N and Odd-Z nuclei tend to decay into Even-Even nuclei by beta decay due to excess rest mass.

Explain where the energy released in fission comes from. How does this differ from the energy released in fusion?

Need to double-check:

Why do odd-N and/or odd-Z nuclei have so many low-energy levels in the nucleus?
