A photoelectron spectrum of a compound containing nitrogen (N), aluminium (Al), and fluorine (F) shows three strong peaks at the following binding energies:
Peak X: ~686 eV
Peak Y: ~399 eV
Peak Z: ~73 eV
Find the best option from the choices given below that best explains the relative positioning of these peaks in terms of binding energy.
In a photoelectron spectrum, the binding energy of a peak depends primarily on the effective nuclear charge experienced by the electron and the electronegativity of the atom from which it is ejected. _________ ____ _________ __________ ____ ____ ________ __________ ___ __________ ___.
