Such a fine article! I hope this template will help those willing to improve it! -The Bold Guy- 15:00, 26 October 2007 (UTC)

English composition
Consider the opening. "Onium compounds are cations derived by the protonation of mononuclear parent hydrides of elements of the nitrogen family (Group 15), chalcogen family (Group 16), and halogen family (Group 17)." Fine. Now we know what they are. But... "Also similar ions derived by the substitution of hydrogen atoms in the former by other groups, such as organic radicals, or halogens, for example tetramethylammonium"! What's that all about? A sentence fragment, formatted like a paragraph, which contradicts the definition?

Further down, "Compounds are known as onium salts." That's a sweeping statement! Surely not all compounds are onium salts. Does it mean that onium compounds are known as onium salts? I'm confused. Really. D021317c (talk) 12:48, 20 November 2007 (UTC)


 * Objection 1: The definition was made less vague. (It should be apparent that there are two kinds. Simple hydrides start the family, and substituted versions extend it.)
 * Objection 2: The missing qualifier was added. "Compounds of an onium cation and some [other] negative ion(s) are known as onium compounds or onium salts." -A876 (talk) 22:49, 18 December 2018 (UTC)

Simple onium cations group order
Why are the Simple onium cations not listed in the numerical order of their groups? Sdiabhon Sdiamhon (talk) 08:57, 26 March 2020 (UTC)
 * Technically only protonated hydrides of pnictogens, chalcogens and halogens, and their substituted derivatives, are onium ions, and these are given in the numerical order of their groups. The remainder belong to the penumbra of the concept, and are given in perceived order of increasing distance from the core. Lavateraguy (talk) 16:29, 26 March 2020 (UTC)
