[edit] A Group NN element is the series...
A large number of the individual group articles start with the phrase "A Group N element is the series..." This sounds ungrammatical to me -- is this some unusual usage I'm not familiar with? I only ask (instead of correcting it) because it's been like this for over a year and no one has corrected them... --Steve Pucci | talk 03:29, 15 June 2006 (UTC)
- Well, I changed them to read "A Group N element is one in the series...". Those lead sentences still seem awkward, but I'm not sure how to fix it. "Group N elements are the series..." seems equally awkward. --Steve Pucci | talk 16:00, 29 July 2006 (UTC)
[edit] Date of new IUPAC system?
It would be of interest to add the date of the "new" IUPAC recommendation, if someone knows it. Dirac66 16:10, 1 October 2006 (UTC)
[edit] F-block
Our standard periodic table contains the f-block, and has four blocks on the periodic table. So we should number the groups in the f-block from 3-16 and following d-block and then into p-block. It will then has 32 group on the periodic table. Then groups number to 18 through just s-block, d-block, and p-block would become the old style just like using Roman numeral through only s-block and p-block. I think that it will happen in the future for IUPAC to number the groups in the f-block. Cosmium 00:48, 24 January 2007 (UTC)
- Wikipedia is not ... IUPAC. Based on the Wikipedia is not a publisher of original thought principal, and the Wikipedia is not a crystal ball principal, that nomenclature would not be appropriate for the article. We don't create the nomenclature used in the periodic table, we just report what the leading scientific bodies use, which right now is the periodic table published by IUPAC on June 22, 2007, which uses groups 1-18 for most of the elements, and has the actinoids and lanthanoids off in their own, ungrouped, area.

[edit] Regarding first section
Ok, I give up: what is a "conch" configuration?
... elements in a group have similar (conch) configurations ...

Good question. The word has no relevance to this subject so I have just deleted it. I checked the article history and someone added it in January 2006 with no explanation. Thanks for pointing this out. Dirac66 22:49, 1 August 2007 (UTC)
P.S. The word "conch" may have been an attempt at "shell" by someone more familiar with another language, since in English a conch is a mollusk with spiral shells, and in French a "couche électronique" is an "electron shell". However the sentence reads better as it now is with "conch" just deleted, and "electron shells" a few words later. Dirac66 00:46, 2 August 2007 (UTC)
