Welcome, Pedro! --Larry Sanger 02:33, 1 November 2006 (CST)
You deleted the part in the chemistry page that distictively states what differentiates chemical reactions from physical: chemical reactions only involve electrons of atoms/molecules. I would like to put that very basic and important thing back!
I added a sentence on the problem you requested. I had removed it because I consider that a description of bonding was probably best left to the "Bonding" section. Do you like it now? Pedro Silva 09:10, 10 November 2006 (CST)
adding electrons to the chemistry page
Yes this is better since the interactions of electrons ARE all that chemistry is about, contrary to physical reactions. That is why I also added EM radiation interacting with electrons (excited atoms/molecules) to mark them as chemical not physical. The ambiguity about chemical reactions has lessened now - though not totally. And yes my worry - as with you - was why in an inttroduction - but since it was there (chemical reactions) it needed be set in its own right and not having mixed interpretations about what a chemical reaction is - contrary to any other kind of reaction. [maybe for understanding better who I am I might be inclined to fill in some more details in my editor page - but so far I am not interested in filling out details of telling that I do have a doctorate in physical chemistruy and a masters in biochemistry/bio-physics as these appear to me mundane to tell. Anyway - this is nice to start with but I will try to formulate an even stronger discription of the chemical reaction - because you omitted the removing of an electron from a substance (hydroxyl-radical for instance) such being chemical as well in nature.
Hi Pedro... Thanks for putting the CZ Live tag back. I had some time to run through "Chemistry" articles and tag them with the Chemistry workgroup tag to get an idea of the articles to be managed by the workgroup.
I mistakenly also included the "CZ Live" with the Chemistry Workgroup tag as I thought we should tag articles that were modified from their original WP forms. After I tagged 200+ articles, Larry correctly pointed out that added category tags does not rise to the condition of a CZ Live tag.
I went back and removed the CZ Live tags I had included, and I'm afraid your article got caught up in the drag net. Thanks for putting the tag back!
