This item contains links to two "portable document format" (pdf) files that you can download, read, and print with the Adobe Acrobat Reader on whatever computer you use. You can use this file to print copies of the periodic table for yourself, groups of students, whatever. What you may not do is sell it, or distribute it on media which you sell. If you are connected to the InterNet and your Adobe Acrobat software is sufficiently current, click on any of the elements in the periodic table from within the Adobe Acrobat reader program to retrieve information about that element from the WebElements site.

The 5-figure version is called webelements_table_5sf_2012-06-07.pdf. This version is appropriate for most uses, in particular for school use and many university requirements. It lists the atomic weights to 5 significant figures, all that is needed for many purposes.

The full version is called webelements_table_full_2012-06-07.pdf. This version is appropriate if you want the atomic weights to have the maximum number of figures. The estimated errors as given by IUPAC are also included. This will suit the professional in particular but is also suitable in many cases for school and university requirements.

These files were updated 07 June 2012 to include the latest IUPAC values.
