Final answer:
Ionic bonds involve the transfer of electrons, while covalent bonds involve the sharing of electrons. Ionic compounds are more rigid than covalent compounds.
Step-by-step explanation:
There are several differences between ionic and covalent bonds. Ionic bonds involve the transfer of electrons, while covalent bonds involve the sharing of electrons. Ionic compounds are generally more rigid, as all the ions are tightly held in place, whereas covalent compounds are more flexible and the molecules can move around to some extent. Another significant difference is that ionic bonds involve the attraction between ions of opposite charge, while covalent bonds involve the sharing of electrons between two atoms.
