This desk accessory gives you over 1600 facts on the elements in the periodic chart. The file that you have downloaded is a demo version of this desk accessory. It includes complete information for the elements 1 thru 10. In addition, it includes useful atomic constants, energy conversion factors, and metric conversion factors. Applications for the first 15 elements are also included with this demo version. Please feel free to copy it and give it to your friends with this information file.
Every attempt has been made to verify and insure that these values are accurate, but no warranty is expressed or implied. Values were obtained and verified with the CRC handbook of Chemistry and Physics, Chemical Principles by Dickerson, Gray and Haight, a HyperCard stack called "ChemElements" by John Cramer (author of Twistor, a science fiction novel), The 1990 World Almanac, and finally, a HyperCard stack named Periodic Table of the Elements by Pisces Publishing.
Version 1.10 is now much faster to draw and update the screens. In addition, several errors that existed in version 1.05 were corrected.
