D) Heisenberg uncertainty principle.

Question

Quizplus · Accepted Answer

The statement "No two electrons can have the same four quantum numbers" is known as the Pauli exclusion principle. This principle states that in a given atom, no two electrons can have the same set of four quantum numbers (n, l, m, s), which describe the energy, shape, orientation, and spin of an electron in an atom. This principle plays a significant role in explaining the electronic configuration and the arrangement of electrons in different subshells and orbitals. Hence, the correct answer is (A) Pauli exclusion principle.
