Quantum mechanics has accurately described the regularities of the periodic table by assigning "quantum" numbers to predict the allowed energy levels. The true statement about quantum numbers is that
A) they describe the position and charge of the electrons in the atoms.
B) no electrons in the world can ever have the same set of quantum numbers.
C) there are never more than 8 different sets of quantum numbers in an atom.
D) no two electrons in the same atom can have the same set of quantum numbers.

Question

Quizplus · Accepted Answer

The Pauli exclusion principle states that no two electrons in the same atom can have identical quantum numbers, which is a fundamental rule in quantum mechanics that helps explain the structure of the periodic table and the behavior of electrons in atoms.
