Question

What does the Pauli exclusion principle state? . . A.Electrons will be added to an atom at the lowest possible level or sublevel. . . . . B. An orbital can contain two electrons only if all other orbitals at that sublevel are empty.. . . . C.An orbital can contain two electrons only if all other orbitals at that sublevel contain at least one electron.. . . . D.Two electrons occupy the same orbital only if they have opposite spins. . . . . E.An orbital can contain two electrons only if all other orbitals at that sublevel are empty..

Answer 1

The Pauli exclusion principle state that : D. Two electrons occupy the same orbital only if they have opposite spins

This happen because he stated that in an atom or molecule, two electrons CANNOT have same four electronic quantum numbers

hope this helps

Answer 2

D.Two electrons occupy the same orbital only if they have opposite spins.
