** 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 = + 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
l = 2 m = - 1 s = - 1/2   9.)  n = 2 l = 1 m = - 1 s = - 1/2
  
10.) Does an electron with this set of quantum numbers exist in the element calcium?
       n = 4
l = 1 m = 0 s = -

Determine the element whose outermost electron (last electron added) is being defined by the following quantum numbers.
11.) n = 1
l =0 m = 0 s = -1/2
12.) n = 4
l =1 m = 1 s = -1/2
13.) n = 3
l =1 m = -1 s = +1/2
14.) n = 4
l = 0 m = 0 s = +1/2
15.) n = 3
l = 2 m = -2 s = -1/2
