MDCAT Physics MCQ #376

  1. Question 1

    Q1. A chemist wants to calculate the energy required for an electron to jump from the first orbit to the second orbit in a hydrogen-like ion with atomic number Z.

    • A) ΔE = (13.6 * Z^2) * (1/2 - 1/1) eV
    • B) ΔE = (13.6 * Z^2) * (1/2 - 1/1) * (1/n^2) eV
    • C) ΔE = (13.6 * Z^2) * (1/1 - 1/2) eV
    • D) ΔE = (13.6 * Z^2) * (1/1 - 1/2) * (1/n^2) eV

    Answer: ΔE = (13.6 * Z^2) * (1/2 - 1/1) eV

    Explanation: Option A uses the correct formula to calculate the energy required for the electron to jump from the first orbit to the second orbit in a hydrogen-like ion.
