Concur. Note also Q17327503. Tortoise0308 (talk) 14:18, 26 November 2016 (UTC)Reply
I see. For example, nitrogen (Q627): period 2 (Q207712) consists of Q17327503; group 15 (Q106675) consists of Q17327492 --Fractaler (talk) 15:50, 26 November 2016 (UTC)Reply
Useless, redundant. In the periodic table, "Group" is a classification. It is enough to claim: nitrogen (Q627) is classified as being in group 2 (and so is a 'member of' group 2). Aggregating, this already lists "members of group 2", and next up "members of a group".
Listing 'Element of a specific group' is no new information. (Also note the 'specific'?!; are there members of non-specific groups?). 'Element of a specific group' is exactly the same as the aggregate 'Members of groups', which is automatically provided. -DePiep (talk) 11:52, 29 January 2017 (UTC)Reply
nitrogen (Q627) is homonym (Q160843) and = 1) Q17327492 and =2) Q17327503. The mathematica model is: nitrogen (Q627) = point (Q44946) on Cartesian coordinate system (Q62912) (2D). Q17327492 (or Q17327503) is point on line (Q37105) (1D). So nitrogen (Q627) = intersection (Q185837) (Q17327492 + Q17327503)

A compound or a substance?

If I understand the definition of a en:Chemical compound well, a chemical element does not qualify because there are no multiple elements involved. I think it should be chemical substance (Q79529). -DePiep (talk) 11:55, 29 January 2017 (UTC)Reply

You would need to make a property proposal - see Wikidata:Property proposal. I assume we'd want a string value, like 1s2-2s2-2p6-3s2 - is there a standard string format for this? ArthurPSmith (talk) 18:19, 22 August 2019 (UTC)Reply

{{Edit request}} Please change Wikipedia name from Elemento to Elemento (kimika) because of article has been page moved.
