This is about chemical compounds, molecules. Here it's about atoms, I think. Correct me if I have wrong information, but afaik CheBi has no chemical elements class, so there is no real answer to the original question.
But yes, those classes if they are not already on Wikidata seems OK to have, and subclass of is appropriate as its semantics is the same in Chebi and in Wikidata. 2014-09-25 20:07 GMT+02:00 Benjamin Good <[email protected]>: > Based on the CHEBI ontology perspective, alcohol is a class with > subclasses like 'aromatic alcohol' which has subclasses like 'benzyl > alcohols' which has subclasses like 'methylbenzyl alcohol' and so on. > > These relationships seem worth capturing and subclass seems like a > reasonable way to do it.
