(d) Energy is required to break a covalent bond.
Answer true or false. (a) An ionic bond is formed by the combination of positive and negative ions. (b) An ionic bond between two atoms forms by the transfer of one or more valence electrons from the atom of higher electronegativity to the atom of lower electronegativity. (c) As a rough guideline, we say that an ionic bond will form if the difference in electronegativity between two atoms is approximately 1.9 or greater.
