Condensation point AND freezing point of oxygen in C and F?

There is one s orbital, and there are three p orbitals, five d orbitals, and seven f orbitals. thus, the answer is b. do not confuse the number of orbitals in a subshell with the number of electrons the subshell can hold. each orbital can hold two electrons, so the capacity of an nf subshell is 14 electrons.

While unproven, it uses facts to support part of a conclusion. it is still factual and has predictive power, however.
