  1. Question 1

    Q1. The energy of the electron in the ground state of hydrogen is -13.6 eV. What is the energy of the electron in the first excited state?

    • A) -3.4 eV
    • B) -6.8 eV
    • C) -1.7 eV
    • D) -13.6 eV

    Answer: -3.4 eV

    Explanation: Using the Bohr model energy formula: E2 = -13.6 / 4 = -3.4 eV.
