Of all the elements in the period table, which atoms have electrons in higher shell levels that do not absorb visible light.?
Or you could say which atoms have electron with energy levels that transmission ALL visible light.
I know that glass does only absorb ultra violet wavelengths of around 350 to 200nm.
So basically any electron in a higher shell in any single atom, that is not in the ground state, that has a electron energy level requirment of around 3.5 to 1.5 electron volts.
Hydrogen shell 2 energy level requirement is 1.5 electron volts.
Also very high purity fused quartz is transparent down to 200nm, which is 6.2 electron volts.
I am trying to figure out what electrons can be in shell levels, in certain atoms, that transmission visible light automatically.
Like in glass.
I am grateful for your help, anything helps even a few words.
