  1. Question 1

    Q1. The ionization potential of hydrogen atom is 13.6 V. What is the ionization potential of Li²⁺?

    • A) 13.6 V
    • B) 27.2 V
    • C) 54.4 V
    • D) 122.4 V

    Answer: 122.4 V

    Explanation: Ionization potential is proportional to Z². For Li²⁺, Z = 3, so ionization potential = 13.6 × 3² = 122.4 V.
