According to the Aufbau principle (SELECT ALL THAT APPLY)
an electron occupies the lowest energy level that can receive it.
no 2 electrons in the same atim can have the same set of 4 quantum numbers
electrons in the same orbital must have opposite spins
orbitals of equal energy are each occupied by one electron before any orbital is occupied by a second electron
all electrons in singly occupied orbitals must have the same spin state.
