The Spin Quantum Number

#### Q. State whether each of the following sets of quantum numbers is permissible for an electron in an atom. If a set is not permissible, explain why. a. n = 1, l = 1, ml = 0, ms = ½ b. n = 2, l = 1, ml = 0, ms = ½ c. n = 3, l = 1, ml = –2, ms = –1/²d. n = 2, l = 0, ml = 0, ms = 1

The Spin Quantum Number

#### Q. Quantum numbers arise naturally from the mathematics used to describe the possible states of an electron in an atom. The four quantum numbers, the principal quantum numbers, the principal number (n), the angular momentum quantum number (l), the magnetic quantum number (ml), and the spin quantum number (ms) have strict rules which govern the possible values. n=2, l=1, ml=0, ms=-1 n=3, l=1, ml=-1, ms=-1/2 n=4, l=3, ml= 4, ms=-1/2 n=4, l=4, ml=-1, ms= +1/2 n=3, l=-1, ml=-1, ms=-1/2 n=5, l=-4, ml=-1, ms=+1/2
