Type “isotope (Q25276), atomic nucleus (Q37147)”: item must contain property “instance of (P31)” with classes “isotope (Q25276), atomic nucleus (Q37147)” or their subclasses (defined using subclass of (P279)). (Help)

Exceptions are possible as rare values may exist. Exceptions can be specified using exception to constraint (P2303).

Correct rank for isotopes
rank in the series (instance of qualifier) of some isotope of some element should be the sum of the atomic number and the neutron number (Help)
Violations query: select (?isotope as ?item) ?rank ?neutron_number ?at_number { ?isotopeclass wdt:P279* wd:Q25276 . ?isotope p:P31 [ ps:P31 ?isotopeclass ; pq:P1545 ?rank ] . ?isotope wdt:P1148 ?neutron_number ; wdt:P1086 ?at_number . filter (?at_number + ?neutron_number != xsd:integer(?rank) ) # check that the ranking number is the sum of the atomic number and the neutron number }

Correct english label for isotopes
english label for isotopes should follow the pattern "[elementname]-[number of nuclides]". If not something is probably wrong. (Help)

Discussion

No bounds

Just as with atomic number (P1086) (see Property talk:P1086#No bounds), I plan to remove bounds from all values of this property as well as they intrinsically do not have an uncertainty. The number of claims that need to be fixed is a bit above 4700. The batch will probably start tomorrow, so if there is any concern, please raise it here… —MisterSynergy (talk) 16:41, 27 April 2018 (UTC)
