November 5, 2007 Dr. Stevens Gen. Chem. 1 Pauli Exclusion Principal each e- has different quantum # -how many 2 p orbitals? -2p nl = 2(1) -m(l) = -l, …, 0, …, l - -1, 0, 1 (labels of orbitals) -3 orientations (vertical, horizontal, 3D) -how many e- can fit in 4f subshell? -4f = nl = 4(3) -m(s) = ½, -½ -m(l) = -3, -2, -1, 0, 1, 2, 3 = 7 orbitals -4f: -14 e- total Hund’s Rule: most stable arrangement of e- is to have maximum UNPAIRED e-
