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". The same applies to "W" (wolfram) for tungsten, "Fe" (ferrum) for iron, "Hg" (hydrargyrum) for mercury, "Sn" (stannum) for tin, "K" (kalium) for potassium, "Au" (aurum) for gold, "Ag" (argentum) for silver, "Pb" (plumbum) for lead, "Cu" (cuprum) for copper, and
Council for Chemical Research has four membership categories: Industrial, Academic, Government Labs, and Affiliates. CCR's mission is "Advancing Chemical Innovation Through Collaboration and Advocacy." CCR serves as a catalyst and partner for initiatives in the field of chemical research, such as the Center for Process Analytical Chemistry and Chemical Industry Vision 2020. CCR produces and sponsors studies such as "Measuring Up: Research and Development Counts for the Chemical Industry" and "Measure for Measure: Chemical R&D Powers the U.S. Innovation Engine". CCR holds an Annual Meeting, an annual New Industrial Chemistry and Engineering Conference (NIChE), and workshops on topics such as Intellectual Property Issues. CCR
