STANDARD Chemistry Quantum Numbers MCQ Question
Pauli’s exclusion principle states that
pairing of electrons does not occur in orbitals of the same subshell until each of them is first singly occupied.
orbitals are filled in order of their increasing energy.
no two electrons in an atom can have the same set of four quantum numbers
none of these.
Correct Answer
Detailed Explanation
Pauli’s exclusion principle states that no two electrons in an atom can have the same set of four quantum numbers, ensuring unique quantum states.
