Answer:
pauli's exclusion principle
☘ The number of electrons to be filled in various orbitals is restricted by the exclusion principle ,given by the Austrian scientist Wolfgang Pauli .
☘ According to this principle ; No two electrons in an atom can have the same set of four Quantum numbers .
☘ Pauli exclusion principle can also be stated as ; Only two electrons exist in the same orbital and these electrons must have opposite spin .
☘ This means that the two electrons can have the same value of three quantum numbers n, l and m1 but must have the opposite spin quantum number .
