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.

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. If not, would another property be better?

Hi all,
why are both the *subclass of* and *instance of* properties set for the
ethanol (showcase) item?
For me ethanol is a single concrete alcohol and it is not a class. There
is only one ethanol, with a single chemical formula and structure, so only
the *instance of* property is right for this item ?

Thank you
