In the Bohr model, the Paschen series of spectral lines is caused by radiation absorbed or emitted as an electron transitions between the 211d excited state and any higher excited state (3rd excited state and higher) of the hydrogen atom. The Paschen series spectral lines all involve infrared photons (9 marks). Using the Bohr model, calculate the energy of the electron when it is in the 2 \"d excited state, in units of electron-Volts (eV). Calculate the energy of the electron when it is in the 31"d excited state, in units of eV. Calculate the energy difference between the 2Ild and 31"[1 excited states, in units of eV
