  1. Question 1

    Q1. A physicist measures the energy levels of electrons in a gas sample. Which quantum number is most relevant to the energy of the electrons?

    • A) Principal quantum number (n)
    • B) Azimuthal quantum number (l)
    • C) Magnetic quantum number (m_l)
    • D) Spin quantum number (s)

    Answer: Principal quantum number (n)

    Explanation: The principal quantum number (n) determines the energy level of the electron, while the other options specify the orbital's shape and orientation.
