Q743
'All the four quantum numbers of two electrons in an atom are not the same.' It is the law of –
A.
Hund's rule of maximum multiplicity
B.
Exclusion Principle of Pauli
AnswerC.
Uncertainty Principle of Hiesenberg
D.
Avogadro's Law
Answer: Option B
Solution
Answer: Option B
Solution:
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.
