Nationality
Why exactly does the article consider him German? According to his Nobel prize biography, he was born in 1866 in Alsace, which was then in France. In 1871 France lost Alsace to Germany, so at that point he did become German. But in 1895 he acquired Swiss nationality, again according to his Nobel biography, and died in 1919. So he was born French, became German at age 5 for 24 years, and Swiss for the last 24 years of his life including most of his professional career. The German and French Wiki articles both describe him as Swiss. —The preceding unsigned comment was added by Dirac66 (talk • contribs) 01:41, 11 April 2007 (UTC).

Alfred Werner was the scientist who was the first to complete the periods of the natural series of elements on the element of the noble gases group
Alfred Werner is the author of the idea of ending all periods in the Periodic System of Elements with an element of the group of noble gases (1905). But for some reason this idea is attributed to Dmitry Mendeleev. Although, Mendeleev himself from 1870 to 1906 invariably ended the periods on the element of the halogen group. This end of the prototype periods on the element of the halogen group was applied by the German chemist Adolf Strecker in 1859. Alex makeyev (talk) 10:57, 30 May 2022 (UTC)
