isn't this just an oversimplified veriosn of hund's first rule as seen in the physics "Hund's rules" page?

Yes, but actually it's the second rule on that page and this simple version is taught to millions (in the United States at least) in introductory chemistry as Hund's Rule while the remaining Hund's rules are taught to relatively few. It's good that Hund's Rule links to this page instead of that one. I'm adding a link to the list of Hund's rules and removing the suggested merge.

Agreed. No merge. I will remove the second merge attempt recently made. --Sadi Carnot 00:34, 19 December 2006 (UTC)[reply]__DTELLIPSISBUTTON__{"threadItem":{"timestamp":"2006-12-19T00:34:00.000Z","author":"Sadi Carnot","type":"comment","level":3,"id":"c-Sadi_Carnot-2006-12-19T00:34:00.000Z-Flying_Jazz-2005-11-04T16:25:00.000Z","replies":[]}}-->

I think something is missing. The reason behind Hund's rule of filing of atomic orbitals in this fashion is that a higher spin state is preffered. The greater the spin state, the more stable the atom. Hence, at each stage of filling there are unpaired elecctrons increasing the spin states and stability. I think I'll add this to the article.

I added a link to a journal, however as I don't have the time to create the full reference, I'll come back later to fix it (or not). Page 1 of the abstract is used. --93.125.198.182 (talk) 11:27, 18 July 2010 (UTC)[reply]__DTELLIPSISBUTTON__{"threadItem":{"timestamp":"2010-07-18T11:27:00.000Z","author":"93.125.198.182","type":"comment","level":1,"id":"c-93.125.198.182-2010-07-18T11:27:00.000Z-Added_link","replies":[]}}-->

The article on carbynes has a rather dubious claim regarding a significant violation of Hund's rules, accompanied by equally dubious claims about strange electron orbitals in carbynes. If an expert in the topic could take the time to check out the article and determine whether the dubious tag I've added is warranted or not, that would be great. There's also a citation needed tag, of course.

Thanks!

I have now answered this at Talk:Carbyne.
