What is the difference between an ionic bond and a covalent bond?

• An ionic bond involves the sharing of electrons, while a covalent bond involves the transfer of electrons.

• An ionic bond involves the transfer of electrons, while a covalent bond involves the sharing of electrons.

• An ionic bond only occurs between nonmetals, while a covalent bond occurs between metals and nonmetals.

• An ionic bond forms molecules, while a covalent bond forms ions.
