What are the abbreviations for all chemical elements and how many are there?

There are 118 elements in the periodic table. http://chemistry.about.com/library/blperiodictable.htm The list of elemental abbreviations can be found here, list alphabetically: http://chemistry.about.com/od/elementfacts/a/elementsymbols.htm Jul 05 09, 4:04 PM

If you want to be pedantic, you may also consider the fact that nobody really knows just how many chemical elements there are. Scientists regularly discover and add elements to the periodic table, so there may be an infinite amount; nobody knows for sure. However, it is true that there are currently 118 "accepted" elements in the periodic table. Jul 05 09, 4:16 PM

Pedantic, but true, 619. Jul 05 09, 4:28 PM

Another pedantic note - new elements are not so much being discovered as being created through nuclear reactions. We have no way of knowing whether the elements so created ever occurred naturally - to this point, all the ones that have been created are so unstable that they would have decayed long ago if they ever did occur in nature. There is, however, an hypothesized 'island of stability' - a range of atomic masses for elements that might be much more stable again. http://en.wikipedia.org/wiki/Island_of_stability Jul 06 09, 1:01 AM
