Describe the Pauli Exclusion Principle in relation to electron configuration.
The Pauli Exclusion Principle dictates that electron configurations in an atom must follow the rule that no two electrons can have the same set of quantum numbers.
The Pauli Exclusion Principle allows for an unlimited number of electrons in a single orbital.
The Pauli Exclusion Principle states that electrons in an atom can have the same set of quantum numbers.
Electron configuration follows the rule that electrons must pair up in the same orbital.
