In a simple model used to analyze UV photoelectron spectra, the orbital energies of the neutral molecule and the cation formed by ejection of an electron are assumed to be the same. In fact, some relaxation occurs to compensate for the reduction in the number of electrons by one. Would you expect the orbital energies to increase or decrease in the relaxati

Sagot :

Answer:

Increases.

Explanation:

The orbital energies increases when the reduction of electron number occurs due to removal from the outermost shell. When we go farther from the nucleus, the energy of orbitals increase. The electron that is farther from the nucleus experience more repulsions because of the shielding effect of other electrons that is present between nucleus and outermost electron. Due to this shielding effect, it is easier to remove the outermost electron which leads to increase  orbital energies.
