molecule</em> to attract electron density to itself. The electronegativity depends upon a number of factors and in particuler as the other atoms in the molecule. The first scale of electronegativity was developed by Linus Pauling and on his scale <strong>gold</strong> has a value of <strong>2.54</strong> on a scale running from from about 0.7 (an estimate for francium) to 2.20 (for hydrogen) to 3.98 (fluorine). Electronegativity has no units but "Pauling units" are often used when indicating values mapped on to the Pauling scale.</p> <p>Use the links in the "Electronegativity" column of the table below for definitions, literature sources, and visual representations in several different styles (examples of which are shown below).</p> <div class="table-responsive"> <table class="pure-table"> <caption><strong>Types of electronegativity for gold.</strong> All values are quoted on the <a href="../periodicity/eneg_pauling/">Pauling</a> scale.</caption> <thead> <tr> <th>Electronegativity</th> <th>Value in Pauling units</th> <th>Periodicity link</th> </tr> </thead> <tbody> <tr class="pure-table-odd"> <td><a href="../periodicity/eneg_pauling/" title="View definition and pictures showing periodicity of Pauling electronegativity">Pauling electronegativity</a></td> <td>2.54</td> <td><a href="../periodicity/eneg_pauling/" title="View definition and pictures showing periodicity of Pauling electronegativity"><img src="../_media/periodicity/tables/sparktables2/eneg_pauling.png" alt="" /></a></td></tr> <tr> <td><a href="../periodicity/eneg_sanderson/" title="View definition and pictures showing periodicity of Sanderson electronegativity">Sanderson electronegativity</a></td> <td>(no data)</td> <td><a href="../periodicity/eneg_sanderson/" title="View definition and pictures showing periodicity of Sanderson electronegativity"><img src="../_media/periodicity/tables/sparktables2/eneg_sanderson.png" alt="" /></a></td></tr> <tr class="pure-table-odd"> <td><a href="../periodicity/eneg_allred_rochow/" title="View definition and pictures showing periodicity of Allred Rochow electronegativity">Allred Rochow electronegativity</a></td> <td>1.42</td> <td><a href="../periodicity/eneg_allred_rochow/" title="View definition and pictures showing periodicity of Allred Rochow electronegativity"><img src="../_media/periodicity/tables/sparktables2/eneg_allred_rochow.png" alt="" /></a></td> </tr> <tr> <td><a href="../periodicity/eneg_mulliken_j/" title="View definition and pictures showing periodicity of Mulliken-Jaffe electronegativity">Mulliken-Jaffe electronegativity</a></td> <td>1.87 (s orbital)</td> <td><a href="../periodicity/eneg_mulliken_j/" title="View definition and pictures showing periodicity of Mulliken-Jaffe electronegativity"><img src="../_media/periodicity/tables/sparktables2/eneg_mulliken_j.png" alt="" /></a></td> </tr> <tr class="pure-table-odd"> <td><a href="../periodicity/eneg_allen/" title="View definition and pictures showing periodicity of Allen electronegativity">Allen electronegativity</a></td> <td>(no data)</td> <td><a href="../periodicity/eneg_allen/" title="View definition and pictures showing periodicity of Allen electronegativity"><img src="../_media/periodicity/tables/sparktables2/eneg_allen.png" alt="" /></a></td></tr> </tbody> </table> </div> <div class="pure-g"> <div class="pure-u-1 pure-u-sm-1-1"> <script async src="//pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"></script>  <ins class="adsbygoogle" style="display:block" data-ad-client="ca-pub-9334432533380510" data-ad-slot="4479092381" data-ad-format="auto"></ins> <script> (adsbygoogle = window.adsbygoogle || []).push({}); </script> </div> </div> <p class="p_first">There are a number of ways to produce a set of numbers representing electronegativity and five are given in the table above.
