  1. Question 1

    Q1. The energy of the nth orbit in a hydrogen atom is given by En = -13.6 / n² eV. What is the energy of the electron in the ground state?

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

    Answer: -13.6 eV

    Explanation: Substitute n = 1 into the given formula En = -13.6 / n² eV to get E1 = -13.6 eV.
