This page displays a chemical periodic table based based upon empirical data within this Chemdex database. You can plot EN grids for individual elements by selecting a single element, or all the elements in a group by selecting the group number, or all the elements in a period by selecting the period number.
Beneath the periodic table are a number of other sets of elements sometimes used when exploring periodicity.
The group (1➝18) labelling is the IUPAC numbering system. The group (G17←G0) labelling is a numbering system decreasing left to right from G17 to G0 denoting the number of electrons required from attached groups to achieve the 8-electron (octet) or 18-electron counts often associated with p- or d-block compounds.
