A) Electrons in their ground state will occupy orbitals in order of their energy level; the lowest energy levels are always filled first.
B) The orbitals of a subshell must be singly occupied with electrons of parallel spin before they can be occupied in pairs.
C) An orbital cannot contain more than 2 electrons. If 2 electrons occupy the same orbitals, they must have opposite spins; i.e. one up spin and one down spin
