    When a hydrogen atom is raised from the ground state to an excited state

    A)  both kinetic energy and potential energy increase

    B)  both kinetic energy and potential energy decrease

    C)  potential energy increases, kinetic energy decreases

    D)  potential energy decreases, kinetic energy increases

    Correct Answer: C

    Solution :

    : Potential energy \[=\frac{KZ{{e}^{2}}}{r}\] As r increases, potential energy becomes less negative. Thus potential energy increases. Kinetic energy \[=\frac{KZ{{e}^{2}}}{2r}\] As r increases, kinetic energy decreases,
