True or false?
a. The allowed values of the quantum number s of an electron are -1/2 and 1/2.
b. The magnitude of the z component Sz of the spin angular momentum of a particle with nonzero spin must always be less than the magnitude | S | of the spin angular momentum.
c. For every two-electron system, the spin factor in the wave function must be antisymmetric.
d. For every system of several fermions, interchange of the labels of two fermions in the wave function must multiply the wave function by -1.
e. An atom of 79Br is a boson.
f. An atom of 3He is a fermion.
g. The magnetic moment of a nucleus is much less than the magnetic moment of an electron.
h. For a proton in an external magnetic field that points in the positive z direction, the MI = -1/2 state is higher in energy than the MI = -1/2 state.
