In each of the following blanks, only enter a numerical value.

1) In a sublevel for which l = 0, there is/are (blank) orbital(s), and the maximum number of electrons that can be accommodated is (blank).

2) In a principle energy level for which n = 3, the maximum number of electrons that can be accommodated is (blank).

3) Give the appropriate values of n and l for an orbital of 3p: n = (blank) , and l = (blank).
