How can you tell if a bond is IONIC or COVALENT? Easy way: All metals = metallic bond Nonmetals and Metals = ionic bond All nonmetals = covalent bond The closer the elements are on the periodic table, their electronegativities are more similar… more likely to form covalent bonds Farther away… greater difference in electronegativity… more likely to form ionic bonds.
