Q: Is it possible for many electrons to become excited when energy is absorbed by an atom or only one or two?

suseMany textbooks such as this one (https://chem.libretexts.org/Bookshelves/General_Chemistry/Chemistry_1e_(OpenSTAX)/06%3A_Electronic_Structure_and_Periodic_Properties/6.02%3A_The_Bohr_Model) describe the absorption of energy by "the electron" and the subsequent emitting of specific frequencies of ...

Q: Fundamental reasons for using vapors for ALD rather than solutions

Paul KolkAtomic layer deposition (ALD) has been developed for many materials, as can be seen from this overview: https://atomiclimits.com/alddatabase/ However, a search for liquid phase ALD gives less results. I know, one reason may be that solvent molecules protect the substrate surface from reactants. ...

I am tempted to flag all these "n factor" questions as off-topic because n factors are not used in actual chemistry.

For what it's worth, I don't think Chemistry has a huge issue with ChatGPT / other generative AI at the moment? There's already a lot of pseudo-correct stuff out there on main site, written and posted by real humans. I feel like most of my comments here nowadays are pointing out errors in posts, and I don't think the voting system is succeeding in quality control. Obviously, this could get worse if people started posting ChatGPT answers here. I haven't seen any of them yet, though.

In chemistry, the eternal question "why?" is superseded by the deeper question "will it go boom?"

I am also surprised that main meta is so quiet about this whole story. Forcing mods to sign Sara's evil plan or have them fired? That seems a bit too similar to Monica's case for me; however, it looks like the remaining main meta community doesn't care anymore.
