For each of the following molecules, (i) write the valence electron configuration (Your answer should be in a fom similar to (o2s), which is the valence configuration for Li) and (ii) detemine if the molecule is paramagnetic (has unpaired electrons) or diamagnetic (does not hae unpaired electrons). If the species are paramagnetic, identify the number of unpaired electrons. (a) Cl21*; (b) O21+ (10 pts)
