Chad's High School Chemistry Videos - 7.4 Quantum Numbers | High School Chemistry

Chad explains everything you need to know about the four quantum numbers: the principal quantum number (n), the azimuthal quantum number (l), the magnetic quantum number (m_l), and the spin quantum number (m_s). He begins with a reminder of the Pauli Exclusion Principle which states that no two electrons in an atom can have the same four quantum numbers. Chad explains what each of the quantum numbers means and the range of possible values they can take. He further explains how to determine the possible sets of four quantum numbers for a given electron in an atom.
