In a given atom no two electrons can have the same values for all the four quantum numbers. This is called

1. Hund’s Rule
2. Aufbau principle
3. Uncertainty principle
4. Pauli’s Exclusion principle

Correct answer: Pauli’s Exclusion principle

Solution

The Pauli's Exclusion Principle states that no two electrons in an atom can have the same set of all four quantum numbers, ensuring unique quantum states for each electron.
