Questions & Step-by-Step Solutions
Which of the following quantum numbers is not associated with the spin of an electron?
Step 1: Understand what quantum numbers are. Quantum numbers are values that describe the properties of electrons in an atom.
Step 2: Identify the different types of quantum numbers. There are four types: principal quantum number (n), azimuthal quantum number (l), magnetic quantum number (m_l), and spin quantum number (s).
Step 3: Know what each quantum number represents. The principal quantum number (n) indicates the energy level, the azimuthal quantum number (l) indicates the shape of the orbital, and the magnetic quantum number (m_l) indicates the orientation of the orbital.
Step 4: Recognize that the spin quantum number (s) specifically describes the spin of an electron, which can be either +1/2 or -1/2.
Step 5: Conclude that the principal quantum number (n), azimuthal quantum number (l), and magnetic quantum number (m_l) do not describe the spin of an electron, while the spin quantum number (s) does.
