Neon has lowest excited energy at 1(s^2)2(s^2)2(p^5)3(s^1) state. And the excitation energy is about 16.9eV.
And next energy is at 1(s^2)2(s^2)2(p^5)3(p^1) state. And the excitation energy is about 19eV.
In Franck Hertz experiment with Neon, current decrease at every 19eV, no 17eV.
Why 19eV? Why not 17eV?
Why neon can't go to the lowest excited state directly. They go to high excited state and transfer to lowest energy. Why?
