Derive the bohr's formula for 7 of a one-electron atom with a nucleus of atomic number z. (recall: (1) v is the energy of the photon emitted (in cm ) when the electron transits from state ny to state nu (ny < n2). (2) a nucleus of atomic number z has z number of protons. (3) since the nucleus is so much nassive than the electron, you can regard the nucleus as being a fixed center around which the electron revolves. in other words, you are not required to consider using the reduced mass concept in this problem.)
