2. (a) Write the ground-state electron configuration for a phosphorus atom.

(b) Write the four quantum numbers that describe all the valence electrons in the

phosphorus atom.

(c) Explain whether a phosphorus atom, in its ground state, is paramagnetic or

diamagnetic.

(d) Phosphorus can be found in such diverse compounds as PCl 3 , PCl 5 , PCl 4 +, PCl 6 – ,

and P 4. How can phosphorus, in its ground state, bond in so many different

arrangements? Be specific in terms of hybridization, type of bonding, and

geometry.
