Electron affinity problems
WebThe electron affinity (EA) of a molecule is defined as Again the problems of adiabatic and vertical values arise. The best values probably are determined by laser photoelectron spectroscopy and laser photodetachment. Both of these methods directly measure a threshold energy for the removal of an electron from the anion. WebChoose 1 answer: \pu {2672 kJ/mol} 2672 kJ/mol, because the electron removed during the third ionization is a core electron. A. \pu {2672 kJ/mol} 2672 kJ/mol, because the electron removed during the third ionization is a core electron. \pu {2672 kJ/mol} 2672 kJ/mol, …
