The accompanying file "The Atomic Elements" is a dictionary file for use with the excellent, freeware, spell-checker program "Excalibur" by Rick Zaccone and Robert Gottshall, which may be obtained from their website at http://www.eg.bucknell.edu/~excalibr/excalibur.html Whilst the standard (i.e. American-English) dictionary that accompanies "Excalibur" does contain the names of the first 103 elements (hydrogen (H) to lawrencium (Lr)), it does not include their associated chemical symbols. Also, since it is an American-English dictionary, it spells "aluminium" (pronounced "al-yu-min-ee-um") as "aluminum" ("a-loo-mi-num") since this is how Americans pronounce it. To address these issues, this dictionary contains the accepted English spellings, as given by the International Union of Pure and Applied Chemistry (IUPAC), of: - 109 named elements and their chemical symbols: hydrogen (H) to meitnerium (Mt). (Elements 104-108 are rutherfordium (Rf), (Db), seaborgium (Sg), bohrium (Bh) and hassium (Hs).) - Temporary IUPAC names and chemical symbols for the discovered elements 110-112. (These are ununnilium (Uun), unununium (Uuu) and ununbium (Uub). See below for IUPAC nomenclature for unnamed elements.) - Temporary IUPAC names and chemical symbols for the recently discovered "superheavy" elements 114, 116, 118. (These are ununquadium (uuq), ununhexium (uuh) and ununoctium (uuo).) - Temporary IUPAC names and chemical symbols for the UNDISCOVERED elements 113, 115, 117, 119 and 120 (ununtrium (Uut), ununpentium (Uup), ununseptium (Uus), ununennium (Uue) and unbinilium (Ubn)) for those who need to write a paper discussing these "missing" elements. - The two isotopes of hydrogen, deuterium (D or [2,1]H) and tritium (T or [3,1]H) - Aludium Phosdex, the Shaving Cream Atom (only joking!) Obviously, this dictionary is only really useful to a dedicated few, namely scientists and students, but I hope that it is as useful to someone else as it has been to me. Should any new elements be discovered/created/named then please let me know. ---------------------------------------------------------------------- Extra information on the elements Should you require extra information on the elements then I would recommend the following web site: http://www.shef.ac.uk/chemistry/web-elements IUPAC nomenclature for unnamed elements Temporary IUPAC names for (un)discovered elements follows a set of easily understood rules. The digits of the element's atomic/proton number are replaced by the following alphabetic sequences: Atomic/proton number digit Alphabetic replacement Chemical symbol letter 0 nil n 1 un u 2 bi b 3 tri t 4 quad q 5 pent p 6 hex h 7 sept s 8 oct o 9 enn e and given the familiar ending "ium." The chemical symbol letter is simply the first letter of each of the alphabetic replacements. For example, the next sequential element to be discovered has an atomic/proton number of 113. The temporary IUPAC name is therefore: 1 un u 1 un u 3 tri t + ium "un-un-tri-ium" or "ununtrium" (the double-i being contracted), with chemical symbol "Uut". ---------------------------------------------------------------------- Laurence Passmore (lmop2@cam.ac.uk) 6th July 1999 The title logos/icons and the program "Excalibur" are hereby recognised as being copyright Medieval Ventures 1992-99 ----------------------------------------------------------------------
