  1. Question 1

    Q1. The energy level diagram of hydrogen atom shows that the energy of the nth orbit is En = -13.6 / n² eV. What is the energy difference between n = 1 and n = ∞?

    • A) 13.6 eV
    • B) 10.2 eV
    • C) 6.8 eV
    • D) 3.4 eV

    Answer: 13.6 eV

    Explanation: ΔE = E∞ - E1 = 0 - (-13.6) = 13.6 eV.
