  1. Question 1

    Q1. The ionization energy of hydrogen atom is 13.6 eV. What is the energy required to remove an electron from the first excited state?

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

    Answer: 3.4 eV

    Explanation: Energy required is 3.4 eV; option D is incorrect because it's the ionization energy from ground state.
