Is it correct to write a state symbol of "g" or "l" for an electron? In the textbook I am currently reading, the state symbol "g" was used for the electron when it described the electron gain by a proton in the gas phase. However, I recall that my chemistry teacher mentioned that electrons should not be given any state symbols, which I agree with. Just like how we do not assign a a physical state to an atom. E.g. We do not say an atom of gold is in the liquid state. I would like to know what is the purpose of assigning state symbols to electrons, if there is one? And would that be chemically accurate?

  • $\begingroup$ I guess a state symbol is only necessary if the electron is in a special state such as solvated when $e^-_{solv}, \; e^-_{aq}$ or something similar would be used. With atoms no state symbol is expected if in their normal state but if gold were in its liquid or vapour state then $\ce{Au_{(l)} , Au_{(g)}}$ respectively would be advisable. (btw. electrons are just as much 'physical matter' as protons or atoms are.) $\endgroup$ – porphyrin Jul 20 '17 at 15:20
