Chemical element of metals. Cu comes from Cuprum, Fe comes from Ferrum, Ag from Argentum. The symbols were not followed by a period (full stop) as with abbreviations. Later chemical elements were also assigned unique chemical symbols, based on the name of the element, but not necessarily in English. For example, sodium has the chemical symbol 'Na' after the Latin "natrium".

Finnish Institute for Verification of the Chemical Weapons Convention Finnish Institute for Verification of the Chemical Weapons Convention The Finnish Institute for Verification of the Chemical Weapons Convention (VERIFIN) is a Finnish institute carrying out several roles in support of chemical weapons disarmament. Established in 1994 as a continuation of a research project started in 1973, it is located within the Chemistry Department of the Kumpula Campus of the University of Helsinki. Funded by the Finnish Ministry for Foreign Affairs, its main task is to develop improved methods of verification of chemical weapons disarmament. The particular approach adopted is to refine analytical chemical techniques for identifying traces of chemical
