what is the general trend of electronegativity on the periodic table
In general, electronegativities of the elements in the same Period increases as you go from left to right across the period. As the nuclear charge increases and the atomic radius decreases across a period, the power of the atom's nucleus to attract electrons to itself increases.ey Concepts. 1  In 1932 Linus Pauling defined electronegativity as the power of an atom in a molecule to attract electrons to itself. 2  Pauling devised a numerical electronegativity scale, based on bond energies. 3  In general, electronegativities decrease down a Group of the Periodic Table.
