- ; Elements File for MWTWIN program
- ;
- ; Comments may be added by preceding with a semicolon
- ; The group heading [ELEMENTS] must exist to signify the start of the elements
- ; Elemental values may be changed, but new elements may not be added
- ; If you wish to add new elements, simply add them as abbreviations
- ; If this file becomes deleted, the MWTWIN program will create a new file
- ; with the default values
- ; Uncertainties from CRC Handbook of Chemistry and Physics
- ; For Radioactive elements, the most stable isotope is NOT used;
- ; instead, an average Mol. Weight is used, just like with other elements.
- ; Data obtained from the Perma-Chart Science Series periodic table, 1993.
- ; Uncertainties from CRC Handoobk of Chemistry and Physics, except for
- ; Radioactive elements, where uncertainty was estimated to be .n5 where
- ; n represents the number digits after the decimal point but before the last
- ; number of the molecular weight.
- ; For example, for No, MW = 259.1009 (±0.0005)
- ;
- ; The values signify:
