Question

An orbital can accommodate maximum two electrons, provided they have opposite spins, this principle is known as :

1) पाउली का अपवर्जन नियम(Pauli Exclusion Principle)
2) हुंड का नियम(hund's rule)
3) ऑफबाउ नियम (Aufbau principle)
4) हाइजेनबर्ग का अनिश्चितता सिद्धांत(Heisenberg's Uncertainty principle)​

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.
