Question

State pauli's exclusion principle. (b) list the quantum numbers (ml and l) for 3d orbitals. (c) write the electronic configuration of cr3+(z = 24).

Answer 1

The Pauli Exclusion Principle states that, in an atom or molecule, no two electrons can have the same four electronic quantum numbers. As an orbital can contain a maximum of only two electrons, the two electrons must have opposing spins.
