Answer
The correct answer is:
(a) Implies that in an atom no two electrons can have identical sets of quantum numbers.
Work Step by Step
In quantum mechanics, the Pauli exclusion principle states that fermions can not have the same quantum state in a system. Since electrons are fermions, the exclusion principle implies that no two electrons can have the same quantum state in an atom.
The correct answer is:
(a) Implies that in an atom no two electrons can have identical sets of quantum numbers.
