What is the velocity of the hydrogen atom after absorbing the photon?

  1. May 31, 2013 #1
    A stationary hydrogen atom with a mass of 1.67 x10^-27 kg absorbs a photon of light with an energy of 10.2eV.What is the velocity of the hydrogen atom after absorbing the photon?

    This is my question:

    Is it true that the atom has no speed since all the energy is completely absorbed at the energy level 10.2eV?
