  1. Question 1

    Q1. The energy difference between the 2nd and 3rd orbit of hydrogen atom is

    • A) 1.89 eV
    • B) 2.55 eV
    • C) 1.51 eV
    • D) 3.4 eV

    Answer: 1.89 eV

    Explanation: Calculate E2 and E3 using En = -13.6 / n² eV, then find the difference: E3 - E2 = -1.51 - (-3.4) = 1.89 eV.
