The electron in an (unbound) hydrogen atom (H(g)) is excited from the ground state to the n=3 state.
Which of the following statements are true and which are false.
A) The electron is closer to the nucleus on average in the n=3 state than in the ground state.
B) The wavelength of the light emitted when the electron returns to the ground state from n=3 is the same as the
C) It takes less energy to ionize the electron from n=3 than it does from the ground state.
D) The wavelength of light emitted when the electron drops from n=3 to n=2 is shorter than the wavelength of light emitted if the electron falls from n=3 to n=1.
E) The first excited state corresponds to n=2.
