<P> The term `` electronegativity '' was introduced by Jöns Jacob Berzelius in 1811 , though the concept was known even before that and was studied by many chemists including Avogadro . In spite of its long history , an accurate scale of electronegativity was not developed until 1932 , when Linus Pauling proposed an electronegativity scale , which depends on bond energies , as a development of valence bond theory . It has been shown to correlate with a number of other chemical properties . Electronegativity can not be directly measured and must be calculated from other atomic or molecular properties . Several methods of calculation have been proposed , and although there may be small differences in the numerical values of the electronegativity , all methods show the same periodic trends between elements . </P>
