Unformatted text preview: For l = 2 and m l = 2,1,0,1,2, it tells you that there are five d orbitals. For l = 3 and m l = 3,2,1,0,1,2,3, it tells you that there are seven f orbitals. Note that this Table also tells you at what energy level a given type of orbital is allowed. For example, there are no 1p orbitals: the first p orbitals begin at energy level 2, for 2p. Also, there are no 1d or 2d orbitals, and there are no 1f, 2f, or 3f orbitals. This is why you can tell how many sublevels there are from the n value. For n = 1, there is only 1 sublevel; for n=2, there are 2 sublevels, etc. The principal energy level, or the value of n, gives you two other pieces of information quickly. The number of orbitals per energy level is just n 2 , while the number of electrons which can fill an energy level is 2n 2 . So for n=2, there are 2 2 = 4 orbitals, and (2)2 2 = 8 electrons can fill this energy level....
