Use the periodic table to select the element from the drop-down menu that has the correct relative electronegativity.Mg >

Electronegativity measures how strongly an atom attracts shared electrons. Magnesium’s electronegativity is about 1.31 on the Pauling scale, while calcium’s is about 1.00, so calcium is less electronegative than magnesium. Be and Al are both more electronegative than Mg.
