Chemists are very familiar with the iconic periodic table. We learn about it at an early stage. One can find these in print in any chemistry text book. It may be amazing to learn that the numbers behind the elements, atomic weights and naturel isotopic abundance, are not set in stone. The IUPAC commission responsible for these values regular update their values, especially as the instrumentation improves. Strangely, in this day and age of computers, it is not yet possible to access all information about the elements in a way a computer can readily understand. This talk will highlight some of the difficulties encountered when attempting to create the PubChem periodic table (https://pubchem.ncbi.nlm.nih.gov/periodic-table/) and highlight steps within IUPAC to improve machine access to and best practices when using the most current atomic weights and isotopic abundances.
