Since the periodic table currently has 7 periods (and will have 7 until element 119, which will be the first element of the 8th period, is "discovered"), consider the electron shell with principle quantum number, n = 7.

a.) Fill-in the blank: _______ subshells have principle quantum number, n = 7. b.) How many orbitals are found in each of the subshells in part a.)?

c.) Fill-in the blank: a total of _______ electrons can occupy the n = 7 shell.

d.) Only the first 4 of 7 electron shells are completely filled in ground states of the largest known atoms (those with atomic numbers 103 and greater). How many electrons occupy each of the first 5 shells (n = 1, 2, 3, 4, 5) when they are full?
