D)+5
E)+6

Question

Quizplus · Accepted Answer

Ionic bonds are more likely to form when the metal ion has a lower oxidation state, as this typically involves the complete transfer of electrons from the metal to the non-metal (in this case, chlorine). In higher oxidation states, covalent or polar covalent bonding is more common due to the involvement of d-orbitals in bonding. Therefore, the +2 oxidation state is most likely to result in the formation of an ionic bond with chlorine.
