1:
a) Using theBohr Model for hydrogen-like atoms, calculate the ionization energyfor helium (He) and lithium (Li).
b) Calculatethe de Broglie wavelength for an electron that has been acceleratedthrough a potential difference of 100 volts. b) Derive a generalexpression for this calculation that is expressed in terms of theapplied voltage only.
c) Determinethe wavelength of the photon emitted when the electron in the n =2state of hydrogen decays to the ground state. Do the same for the n= 3 to n = 2 state transition. Is this photon visible? What seriesdoes it
