In general, the energy levels of the entire matter are fully occupied or empty, for if an energy level for electrons is only partially [...] partially occupied, it is immediately taken up by electrons of another molecule or atom, in general by the atoms involved combining. Atoms and molecules which are not in their ground state are therefore highly [...] plasma, many atoms and molecules are not in their ground state but in an excited state, i.e. the electrons are either excited to a higher energy level are completely removed from the atomic shell.
