Caution with nuclide items

A lot of nuclide items are not labeled yet. Only create items after doing a thorough check of a few languages. If you create a nuclide please add it to the list Wikidata:Physics_task_force/List_of_nuclides. Especially the Dutch Wiki has a lot of nuclide articles. --Tobias1984 (talk) 14:45, 23 August 2013 (UTC)
