Which ion was formed by providing the second ionization energy to remove an electron? Ca2+ N3– Fe3+ S2–

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.

Sorry i dont understand the question can you rephase it?
