CHM120H5 Final: CHM-120-notes

Which of the following are permissable sets of quantum numbers for an electron in a hydrogen atom? The atom may be in an excited state (ie. the electron need not be in its ground state). Choose all of the correct possibilities. n = 5, l = 3, ml = -4, ms = -1/2 n = 4, l = 4, ml = 0, ms = -1/2 n = 4, l = 2, ml = -1, ms = -1/2 n = 6, l = 5, ml = +3, ms = -1 n = 3, l = 1, ml = 0, ms = -1/2 n = 1, l = 0, ml = 0, ms = -1/2 n = 5, l = -4, ml = -3, ms = -1/2 n = 5, l = 1, ml = -1, ms = -1/2 n = 4, l = 3, ml = +2, ms = +1/2 n = 4, l = 0, ml = 0, ms = -1/2 Incorrect: Your answer is incorrect.

Which of the following sets of quantum numbers are not allowed? For each of incorrect set, state why it is incorrect.

a. n=3, l=3, m_l=0, m_s= -1/2

b. n=4, l=3, m_l=2, m_s= -1/2

c. n=4, l=1, m_l=1, m_s= +1/2
