Periodic table (text only)

Article on other languages:

This text-only table is a version of the large table designed for printing atomic mass data. Colors representing chemical series have been removed, and all links have been removed. The least significant digit has been dropped if its uncertainty is greater than 1. Rounding was performed in these cases.
