The accompanying file "The Atomic Elements" is a dictionary file for use with the excellent, freeware, dictionary 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 elements and their chemical symbols; hydrogen (H) to meitnerium (Mt)
	 Elements 104-108 are: rutherfordium (Rf); dubnium (Db); seaborgium (Sg); bohrium (Bh) and
	 hassium (Hs). 
¥ Three 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]
¥ 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.

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 is simply the first letter of each of the numerical replacements. For example, the next sequential element to be discovered is 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."
