see my paper, there is illustration in the paper.
extra electrons come from other ionized atoms. in excited gas, a lot atoms lost electrons.
it's OK. I am not good at English, might have misspelled a lot
Angular momentum is quantized in all atoms, even hydrogen, which has only one electron.
If you think it's because of a variable number of electrons, let's see the model that predicts this. Give us the math.
------------------------------------
I answered this.
In excited hydrogen gas, not all H atom has one electron. some H atoms have more than one electrons.
the "Angular momentum" is quantized due to the different number of electrons, form 0, 1, 2, ... to 8
all other quantized parameters are due to the same reason. including the spectrum.
My paper can not give the math of "angular momentum".
It can only calculate the spectrum of H gas, and the ionized helium gas.
the spectrum of H atom include so many wavelengths light.
they are emitted by many H atoms, not by a single one H atom!
or we should say, they are emitted by the one bottle of H gas, not by one H atom.
if we can detect the spectrum of a single one H atom, then, we can't see the spectrum(only can see one wavelength light).
Spectrum is a group effect of mass atoms, not the effect of a H atom.
