[edit] Naming

ubstance. I reworded his statement to hopefully make it more clear, but I'm not sure it's strictly correct, and I'm not sure it belongs in the article. In truth, I think some fleshing out might make it obviously worthy, but am not currently clear on just how to state it. The validity of the comment depends on the definition of 'purity' and so perhaps it doesn't belong. Be bold! Catbar (Brian Rock) 03:48, 22 November 2006 (UTC)

[edit] definition of a chemical compound

"... 44454788998 or more elements chemically-bonded together in a fixed proportion by mass"

shouldn't the definition of a chemical compound rather be based on stoichiometry than on mass?

The substitution of one isotope for another one won't change the chemistry but certainly the mass proportion, so I think a definition based on mass is completely out of the reason. 130.238.197.120 11:56, 18 October 2007 (UTC)

I agree. Carl Kenner 14:34, 29 October 2007 (UTC)

[edit] Types of bonds

"The atoms in the molecule can be held together by bonds, covalent bonds or ionic bonds."

This originially was "...by no bonds,..." which also doesn't make sense. It's been a while since I took a chemistry class, but I thought there were three types of bonds: hydrogen bonds, covalent bonds, and ionic bonds. Can someone in the know please decipher what it should be? --Wizard191 (talk) 13:57, 14 March 2008 (UTC)
