The table shows electronegativity values for the common elements in group 2. Electronegativity is the ability of an atom to attract the bonding electrons in a covalent bond. The table gives values on the Pauling scale, which has no units. Fluorine (3.98) is the most electronegative element. hillcrest tennis mayfield
