Question

Quizplus · Accepted Answer

The exclusion principle, also known as Pauli's exclusion principle, states that in an atom, no two electrons can have identical sets of quantum numbers. This means that there cannot be two electrons in the same energy level with the same spin state. This principle helps to explain a variety of phenomena, from atomic structure to chemical bonding.
