  1. Question 1

    Q1. The energy of the electron in the first Bohr orbit is -13.6 eV. What is its energy in the second Bohr orbit?

    • A) -3.4 eV
    • B) -6.8 eV
    • C) -13.6 eV
    • D) -27.2 eV

    Answer: -3.4 eV

    Explanation: Energy is proportional to 1/n^2; for n = 2, energy = -13.6/4 = -3.4 eV; option B is for n = √2.
