An unknown element X forms a compound with chlorine: XCL2. Predict the chemical formula of the compound that element X makes with oxygen. Justify your answer.

Hold on i’m gonna go check really quick

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.
