Disputatio:Systema periodicum

message: Next little point - the Group numbers. Roman Numerals are fine in principle here, but regrettably they led to confusion when used in Anglice:
"Group numbers
"There are three systems of group numbers; one using Arabic numerals, another using Roman numerals, and one using a combination of Roman numerals and Latin letters. The Roman numeral names are the original traditional names of the groups; the Arabic numeral names are a newer naming scheme recommended by the International Union of Pure and Applied Chemistry (IUPAC). The IUPAC scheme was developed to replace both older Roman numeral systems as they confusingly used the same names to mean different things."
The Roman numerals system also had no numbers for all the transitional metal groups (those not-very-rare metals such as Fe and Cu).
Let's add (or, even more radically, substitute) the modern standard "Arabic" numerals.

Comment. Actually there is a Roman numeral system for the groups.
Arabic numerals	1 	2  	3   	4  	5 	6  	7   	8   	9   	10  	11	12 	13  	14 	15	16 	17  	18
Roman numerals 	IA	IIA	IIIB	IVB	VB	VIB	VIIB	VIII	VIII	VIII	IB	IIB	IIIA	IVA	VA	VIA	VIIA	0
There is no problem for that system. It is just that IUPAC does not approve of this system anymore.

replies: text: :The disputatio is a good place to bring up issues, rather than bring up revert wars of "this means this" vs "no it doesn't".  Also it's a better place to make sure comments are seen than edit summaries, so others can learn and not repeat the same mistakes.    —Mucius Tever 05:11, 26 Februarii 2010 (UTC)

thread_title: Seria chemica tabellae periodicae

message: Yejianfei, cur exemplum delevisti? A deletion of that size (8064 octeti) would cost Vicipaedia four points in the 1K rankings at Meta and several points in the 10K rankings. Perhaps you're going to insert a better table? If so, please work from the present version, as I've made improvements while reverting. IacobusAmor (disputatio) 19:55, 19 Februarii 2017 (UTC)
replies: text: Wait! I didn't see the new table. Maybe it's better; let others decide, but do work from the present version. Still: the reduction does cost Vicipaedia those points. Perhaps you'd like to make up the loss by adding 8000 or so bits of Latin text. IacobusAmor (disputatio) 19:58, 19 Februarii 2017 (UTC)
replies: text: :Yes, I thought you'd notice that! A relevant question is whether the new table, designed as a formula, is to be used on any other page. If not, it might possibly be "subst"ed on to this page. But better to wait and consider rather than acting hastily.

text: :Hence (not meaning to edit-war, mi Iacobe) I have reverted to Yejianfei's version, just for the moment, to see whether he will improve it further. Your edits remain in the history and could be transferred to :Formula:Systema periodicum if that seems the best way to go.
