a) According to the Bohr model for a hydrogen atom, what is the energy di erence between the ground state (n = 1) and each of the rst (n = 2), second (n = 3), and third (n = 4) excited states? (Note: the electron always starts in the ground state). What wavelength of light, in nanometers, is needed to cause each of these excitations? b)The Bohr model can also be used to describe other one-electron atoms such as He+, Li2+, etc. How does the energy for these excitations change qualitatively as the nuclear charge increases?

Question

a) According to the Bohr model for a hydrogen atom, what is the energy di erence between
 the ground state (n = 1) and each of the rst (n = 2), second (n = 3), and third (n = 4)
 excited states? (Note: the electron always starts in the ground state). What wavelength
 of light
, in nanometers, is needed to cause each of these excitations?

b)The Bohr model can also be used to describe other one-electron atoms such as He+,
 Li2+, etc. How does the energy for these excitations change qualitatively as the nuclear
 charge increases?
