Smile Does anybody know the energy shells eV for glass, and SOLID carbon

Glass does not absorb any light, exept UV.
but what is the eV for the glass electron to get excited and leave the ground state, and move up to shell level 2, or energy band 2.
Also when carbon electrons are in the ground state, how much eV from light or any other EM radiation does it take for the electron to jump to shell/ energy band 2, and to shell 3, up to the point where the electron would leave the atom.
Thank you for your help, anything helps even a few words.

You didn't respond to either my explanation or a similar one from topsquark in your last composite thread.

The optical characteristics of transparancy or opacity is a very complicated one.

All single atoms are transparent, but when there is a mass of them there are several different effects responsible for the optical properties.

Photon absorbtion by electrons is only one.

There is also a question of a regular structure - or lack of one.
The light can be dispersed by reflection / diffraction between crystal faces.
This is what happen is carbon.
In vitreous state materials eg glass there are no crystal faces.

But I suggest you start at the beginning and ask yourself what can happen if a stream of photons is directed at

1) a single atom

2) a regular array of atoms (a crystal)

3) a random groupoing of atoms (a glass)

Note also the difference between elements and substances, atoms and molecules.

Smile Thank you for answer.

Dear Studiobot,
Thanks for your answer, I did respond to your last question it was at the bottom of the 5 questions, I asked.
Since a few days ago found out that different atoms have different energy's in eV to move to higher energy bands, and its not the amount of electrons in the atom that effects absorption, its the energy levels for sure.
So is it known what energy levels for electrons in glass atoms are in eV to move to a higher shell level.
The reason I want to know about eV levels in carbon because it is the material the human body is made from.
I am studying neuroscience, and how to make human tissue less opaque, if it possible to do.
Thank you for your help.
