Quantum numbers are used to uniquely identify an electron in an atom. The Pauli exclusion principle states that no two electrons in an atom may have the same set of four quantum numbers List a possible set of four quantum numbers (n,l ,ml ,ms ) in order, for the highest energy electron in gallium, . Refer to the periodic table as necessary. Enter four numbers separated by commas (e.g., 3,2,-2,1/2).
