Could you please give reasons as to why you choose those answers. Can you have as many protons and neutrons as you want in each energy level of the shell model? Choose more than one answer if necessary. A. No, the occupancy of the levels obeys Pauli's exclusion principle. B. Yes, protons and neutron are bosons and there is no restriction in their occupancy. C. No, no level can have any protons or neutrons with the same quantum numbers. D. No, protons and neutrons do not get along. E. Yes, both protons and neutrons are free particles since 1990 and can go wherever they want.
