• Note that there is a transition to a 1s 2 2s 2 2p 5 3s 1 state that also corresponds to [itex]\Delta J=0[/itex] (the energy is 16.85 eV), however that means that the angular momentum of the excited electron has to change (i.e. [itex]\Delta l=-1[/itex]), which is also probably not very likely.
• Ionization energy is measured in the gas state so that there are no surrounding atoms or ions that might affect the value for the ionization energy. Since the easiest electron to remove will always be removed first (since ionization energy is the minimum energy required to remove an electron) it follows that IE1 < IE2 < IE3 < … where IE1 is the first ionization energy, and so forth.
• The energy states of the transitions can lead to emissions over a very large range of frequencies.
