User talk:Woodenchemist
Hi Woodenchemist, welcome to Wikipedia. You might be interested in Wikipedia:WikiProject Chemistry and its daughter, Wikipedia:WikiProject Chemicals. One of the best ways to keep up to date with chemistry happenings on Wikipedia is to add these two pages to your watchlist - all the action happens on the talk pages Wikipedia talk:WikiProject Chemistry and Wikipedia talk:WikiProject Chemicals.
I had to undo a few of the edits you made, adding some of your very nice images to articles: chromic acid and tetraethyllead. You've obviously mastered the art of making a good-looking picture of a molecular model, some of the best work I've seen, but in these two cases, the actual chemistry was wrong - the molecules were not the right shape.
If you need any pointers on where to find reliable information on the structures of molecules, just ask at my talk page, or post a message at the chemistry Wikiprojects. It can sometimes be difficult or impossible to find the true structure(s) of a molecule, but more often than not there's plenty of information out there.
I hope you enjoy contributing to chemistry at Wikipedia!
See you around
