They are occupied by two electrons at a time and (in the case of helium), each hydrogen atom can contribute only one electron

Should it be Hydrogen instead of helium?

Also, should the abbreviation MO really be used? Just a clarity issue

As long as the term "Molecular Orbital (MO)" is introduced early in the article, the abbreviation MO shouldn't be a problem. This abbreviation is very commonly used.

"Antibonding (or anti-bonding) is a type of chemical bonding. An antibonding orbital is a form of molecular orbital (MO) that is located outside the region of two distinct nuclei[1]." This is not true in my opinion, for two 2p orbitals, the antibonding MO has a volume which lies between the two nucleus. Also, referencing a Youtube video? Really? [Edit by Kinkreet 5 Dec 2010]

I have now rewritten the intro and fixed the above problems. Dirac66 (talk) 01:41, 15 September 2014 (UTC)

Requested move[edit]

AntibondingAntibonding orbital – The term Antibonding is not used as a noun in chemistry, but rather as an adjective to modify Orbital. The article is actually about Antibonding Orbitals. Dirac66 (talk) 01:46, 15 September 2014 (UTC)

"antibonding molecular orbital" gets "About 119,000 results".
"antibonding orbital" gets "About 65,100 results"
These comments will naturally be superseded by comments of editors that have an understanding of the chemical principles involved. Gregkaye 09:21, 15 September 2014 (UTC)
Yes, I can agree that including the word molecular would be better. Other editors please choose between three alternatives: Support Antibonding orbital or Support Antibonding molecular orbital or Oppose any change. Dirac66 (talk) 12:00, 15 September 2014 (UTC)
  • Support antibonding molecular orbital sounds a bit clunky to me but if it's the more common phrase then we should use that. I would ask that the alternatives are added as redirects. Project Osprey (talk) 14:38, 15 September 2014 (UTC)
  • Consensus: I think the above discussion can be considered as a consensus for Gregkaye's suggestion of Antibonding molecular orbital. Of three editors participating in seven days, Gregkaye opposed the original suggestion of Antibonding orbital but suggested the alternative of Antibonding molecular orbital. Project Osprey and I have accepted this alternative as an improvement. So I will carry out the move to Antibonding molecular orbital, and add redirects from both Antibonding and Antibonding orbital.

  • Support I've never heard of "antibonding" used as a noun by itself. It's nowhere near specific enough for this article's title; it could refer to a psychological problem between mothers and their newborn babies. I think the adjective "molecular" in the new title would have been better left out, but it is a lot better than "Antibonding". --ChetvornoTALK 19:54, 22 September 2014 (UTC)
  • Removing the RM tag from this request, since a move seems to have been carried out a long time ago. Dekimasuよ! 01:21, 20 October 2014 (UTC)
