 Atomic Names and Symbols

Every element has a one- or two-letter abbreviation based either on its English name or its Latin or Greek name.

The table below lists the atomic numbers, symbols, and names of all the elements, with the derivations for the symbols which are not of English origin. A complete list of derivations of the names of the elements may be found here.

Generic Names

Generic names and symbols are given to artificially produced elements which have been reported but not yet assigned official names. These names and symbols are assembled from the digits in the atomic number of the element, plus the ending.

Thus, element 110, before it was given the name "Darmstadtium" was known as ununnilium (Uun), element 111 was unununium (Uuu), element 113 is ununtrium, and so on.

AWS A5.14 Inconel Filler Metal 65 (ERNiFeCr-1)

ERNiFeCr-1 is used for gas-tungsten-arc welding of Incoloy alloy 825 and other nickel-iron-chromium-molybsenum-copper alloys of similar composition. The weld material is highly corrosion resistant, particularly in reducing chemicals such as sulphuric and phosphoric acids. It is used in the chemical industry, oil and gas piping factories and it is used for pollution control purposes.

AWS A5.11 Inconel Welding Electrode 152 Specifications (ENiCrFe-7)

Electrodes of Inconel 690 are used for welding the nickel-chromium-iron alloy with UNS Number N06690. Typical specifications for the nickel-chromium-iron base metal are ASTM B166, B167, and B168. The electrodes may also be used for the welding of nickel-chromium-iron alloys to steels and stainless steels, and for corrosion-resistant overlays on steels. Specification of values for boron and zirconium are helpful in reducing the tendency for ductility dip cracking. Electrodes through the 1/8 in [3.2 mm] size can be used for welding in all positions. Electrodes larger than that are used only in the flat and horizontal positions.
