You can plot <strong>VN</strong> grids for individual elements by selecting a <strong>single element</strong>, or <strong>all the elements in a group</strong> by selecting the group number, or <strong>all the elements in a period</strong> by selecting the period number.</p> <p>Beneath the periodic table are a number of other sets of elements sometimes used when exploring periodicity.</p> <p>The <strong>group (1➝18)</strong> labelling is the IUPAC numbering system. The <strong>group (G17←G0)</strong> labelling is a numbering system <em>decreasing</em> left to right from <strong>G17</strong> to <strong>G0</strong> denoting the number of electrons required from attached groups to achieve the 8-electron (octet) or 18-electron counts often associated with <em>p-</em> or <em>d-block</em> compounds.</p> <h2>Chemical periodic table</h2> <div
