  1. Question 1

    Q1. The energy of the electron in the nth orbit of hydrogen atom is given by En = -13.6/n^2 eV. What is the energy of the electron in the ground state?

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

    Answer: -13.6 eV

    Explanation: Ground state energy is -13.6 eV; option B is incorrect because it's the energy of a free electron.
