201- If the electron in a hydrogen atom is excited from the ground state to the level $n = 5$, which statement is correct?
  1. [(1)] For the ionization of this atom, less energy is needed compared to the ground state.
  2. [(2)] The electron in this state has less energy compared to the ground state and is farther from the nucleus.
  3. [(3)] The wavelength of the emitted light when returning to the ground state is greater than that for returning to $n = 2$.
  4. [(4)] The energy required to remove this electron from the atom is the ionization energy of the first shell of hydrogen.
