CHEM 1E03 TUTORIAL #5 Solutions _____________________________________________________________________ Page 1 of 2 1) a) Consider the following atomic orbital designations: 6s, 1p, 4d, 2d, 3p, 5p, 2s. Which of these are not possible? Why? 1p is not allowed because p means l = 1, but l must be less than n . 2d is not allowed because d means l = 2, but l must be less than n . All the other listed orbital designations (6s, 4d, 3p, 5p, 2s) are allowed. b) Which of the following sets of quantum numbers ( n , l , m l ) are not allowed? (2, 0, 0) (1, 1, 0) (2, 1, 1) (1, 0, 1) (2, 0, 0) corresponds to 2s and is allowed. (1, 1, 0) corresponds to 1p, which is not allowed (see (a) above). (2, 1, 1) corresponds to 2p and is allowed. (1, 0, 1) would correspond to 1s, but m l = 1 is not allowed for s orbitals. The absolute value of m l must be less than or equal to l . 2) a) Which of the following gaseous atoms is smallest : P, Cl, Ca, or Si? The atoms Si, P, and Cl are in period 3; Cl is the smallest of these three, since size
