Why do some elements form covalent bonds while others form ionic bonds?
why do some elements form covalent bonds while others form ionic bonds? In an Ionic bond, an atom of one element has attracted an electron off an atom of another element. This happens because the first atom has a much higher electronegativity. In the case of covalent, the electronegativities of the 2 elements are not different enough for one atom to attract an electron off the other atom. The atoms share a pair of electrons.
