There doesn't appear to be a general thread for posting artwork so let's start one.
I'll start us off with my alternate Periodic Table from the DSA timeline...

Interesting, though the fact that you'd have a very odd irregular increase in valence electron count and atomic mass after the 3rd column* makes me wonder about it's long term survival.
*Going roughly 1, 2, 18 and then decreasing to 3 from there.
At some point it just feels someone's going to say 'why don't we just put the Alkali Earths and Metals at the top so that we go from 1 electron and count upwards?'
and you've effectively just rotated the OTL table by 90 degrees and mirrored it.
Though even that would still be interesting.
I don't quite know what you're indicating with the 1, 2, 18 comment. Basically it is a flipped and rotated version of the Janet Periodic Table with the 1s & 2s on the same column rather than separate.

Really interesting idea! How are the atoms sorted?
Well, there's several reasons that one attracts strong criticisms from Chemists.
Suffice to say this makes it rather harder to read off trends in the properties of atomic weight and so forth- something compounded by having Hydrogen in the same period as the Halogens which is... yeah not exactly accurate.
It actually raises a rather serious question about how you even come to this as the standard table in the 30s- the Janet table relies on a quantum understanding of electron orbital filling for its reasoning, whereas electron count with a couple of exceptions follows atomic mass- indeed the table was actually ordered based on that, but with a couple of elements transposed to ensure properties were the same down the column (Chlorine in particular IIRC).
Unless this is a much later table that supercedes an earlier one, I'm struggling to see how you'd come up with this arrangement first.
EDIT: Oh god your reasoning is a little out- the valence electrons are not the s shell, it's the outermost partially filled shell.
For Aluminium, this includes both the s and p orbitals,
for Iron it's the s and d orbitals, and it's definitely not accurate to state that the s shell is filled after the d shell as there's some complicated electron shell filling patterns going on which basically mean that for a couple of configurations you end up with the s-shell electrons being transferred to the d orbitals but otherwise you have a filled s shell but partially filled d shell.
Other than Hydrogen & Helium? (for which you'll note my version makes an allowance)
Ah, slightly misread that yes. I'd still consider it to be problematic, mainly because the transition metals of the 3d orbital do actually involve the 4s orbital in a lot of interactions and the 5s basically doesn't come into it.Take another look at the alignment - they don't go lighter - 1 & 2 are shifted one higher than in the traditional periodic table - which is fine, since it's really a spiral anyway.![]()
True indeed, it's really why I tend to prefer the 'floating at the top of the table' layout as it doesn't make sense to try and force it into one column or another.There is no place that is exactly accurate for Hydrogen. I could make arguments for it's traditional location, for where I have placed it, and for above Carbon.
Well, that makes more sense, not that the physicists really do much with the periodic table outside the radioactive isotopes anyway.This is a much later table, and it is an attempt at compromise between chemists and physicists.
Yeah, it's actually a really interesting process where the covalent bonding process for aluminium (and carbon, nitrogen and oxygen for that matter) involves a hybridisation of the s and p orbitals to form a set of identical sp orbitals which can then have identical overlap rather than the different shapes of the s and p orbitals. A lot of this comes down to molecular symmetry.Hmmm, didn't know that one.
Not strictly accurate, the blocks are still ordered by valence electrons (so you'll hear people talking about group 3 Transitional Metals, or group 5 metals), but the normal rules for electron shell filling are suspended for the transition metals and it's just sort of assumed that the d block doesn't get involved when you get to groups 13-18.Which is part of why I don't believe that they reference valence number for the transitional metals.
Cool, somewhere I can dump all my crap:

On that note, anyone heard from Big Tex? Been almost a year since the last time he posted, which was about an attempted account invasion. Hope he’s okay... Haven’t heard from him.
