  1. Question 1

    Q1. The energy levels in a hydrogen atom are given by the equation E_n = -13.6 eV/n^2. What is the energy of the electron in the ground state?

    • A) -13.6 eV
    • B) -6.8 eV
    • C) 0 eV
    • D) 13.6 eV

    Answer: -13.6 eV

    Explanation: For n = 1, E_1 = -13.6 eV; negative energy indicates bound state.
