Electronegativity Trends

Periodic table of electronegativity using the Pauling scale. The tendency of an atom in a molecule to attract the shared pair of electron towards itself is called its electronegativity. What really powers a battery is the difference in electronegativity between the materials. Electronegativity values for each element can be found on certain periodic tables. the trends in electronegativity in the periodic table. Trends in Electronegativity in Periods of the Periodic Table. The ability of an atom in a molecule to attract shared electrons is called electronegativity. The higher the electronegativity of an atom, the greater its ability to attract shared electrons. The electronegativity of atoms decreases as you move from top to bottom down a group in the periodic table. GROUP TRENDS: Within a group of the periodic table, electronegativity decreases from top to bottom. Electronegativity is a measure of the attraction an atom involved in a bond .
