Question

question 21 (1 point)
what is the pauli exclusion principle?
no two electrons in the same atom can have the same quantum state.
no two electrons in an atom can have the same spin number.
only two electrons in the same atom can have the same quantum state.
only pairs of electrons in an atom can have the same quantum state.

Explanation:

The Pauli exclusion principle states that no two electrons in the same atom can have the same set of quantum numbers (i.e., the same quantum state). This principle is fundamental in understanding electron configurations in atoms.

Answer:

No two electrons in the same atom can have the same quantum state.
