So in 3 years from now, when this general has 60-70 individual posters a thread I can say I was the first
Connor Reyes
what was the point of this thread?

So I'm trying to analyze the trend of electron affinities of atoms using the qm model of the atom. I get why the period two elements have a less negative EA than the period three based off of proximity of electrons in the 2p orbital vs the 3p orbital, but then as the principal quantum magnetic number increases the atomic radius increases more so and thus the EA becomes less negative. Except for with the Nitrogen family, as astatine's EA is lower than phosphorus' but germanium is higher than silicon, selenium's is higher than sulfur's and so forth. Why does this occur? And why is it corrected for bismuth, which also coincidentally breaks the half filled p orbital trend in being harder to accept an electron?

Hey guys I need to write a research proposal in the field of nanomaterials or supramolecular chemistry. It's just for an exam I'm not actually going to end up doing it. So currently I'm looking for a problem to solve and I came up with the separation of metals from eachother. Apparently getting to really high purities is pretty difficult since the separation of some metals from eachother is pretty impossible. I was thinking that maybe with some specific nanostructure or supramolecular assembly you could get a high affinity for a specific metal ion but I need to look more into it. Does anybody else maybe have any ideas?
There clearly is something weird going on with the p-block. I'm not a quantum chemist but I think the trends are not supposed to look like that
