The number of generated electron-hole pairs is proportional to the number of absorbed photons. Since the energy of each photon is ħω, the generation rate is given by: (6.27) where Qe is equal to the average number of electron-hole pairs produced by one photon.

In chemistry, an electron pair or Lewis pair consists of two electrons that occupy the same molecular orbital but have opposite spins. Gilbert N. Lewis introduced the concepts of both the electron pair and the covalent bond in a landmark paper he published in 1916.

Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons.

Electropositivity can be defined as the tendency of an atom to donate electrons to form positively charged cations. The property to form positively charged cations is most probably exhibited by the metallic elements in the periodic table, especially the alkali metals and the alkaline earth metals.

When an X-ray photon is absorbed by an atom or molecule, it usually knocks out one of the electrons from deep inside the atom through a process called photoionization or, more specifically, inner-shell photoionization. This process leaves behind a core-excited atom or molecule that will decay further.

Are photoionization from ground and recombination to ground consider a reversible processes in the thermodynamic sense?

Ignoring any quantum broadening effects, consider a closed system of one Hydrogen and one ionizing photon. The photon could ionize the atom, which would later recombine emitting the same energy photon that was absorbed. This seems to be a cycle that ends in the same state, therefore I'm guessing each ionization and recombination must be reversible processes.

Now recombinations do not always end up in the ground state. Then the recombination to a different level other than ground would lead to a cascade that would result in at a minimum of two photons, with at most only one of ionizing energy. Given enough time and repetition of recombining to a state other than ground there will eventually be no ionizing photon.
