Electronegativity An atom’s electronegativity value refers to the amount of
“pull” that an atom’s nucleus exerts on another atom’s electrons when it is
involved in a bond. Atoms of different elements typically have different
electronegativities. As you move across the periodic table from left to right,
electronegativity increases. As you move down a column (group) on the
periodic table, electronegativity decreases. Electronegativity increases as
