** Each question below corresponds to the number in the table. **
For 1 – 3, give the four quantum numbers for the electron indicated.

1.)  n =             l =              m =            s =
2.)  n =
l =              m =            s =
3.)  n =
l =              m =            s =
For 4 – 9, draw in the electron with the following sets of quantum numbers.
4.)  n = 3
l = 2      m = 0               s = + ½                        5.)  n = 3          l = 1        m = + 2        s = + 1/2
6.)  n = 4
l = 1      m = + 1            s = - 1/2                         7.)  n = 2          l = 1        m = 0           s = + 1/2
8.)  n = 3
