Ionic bonding is a non-molecular interaction, in which every cation, every metal ion, is electrostatically bound to every other anion in the lattice. Starch is a carbohydrate molecule made up of smaller sugar molecules bonded together by weak chemical bonds called linkages. Low Solubility Many covalent compounds are not soluble in water, which means that they do not dissolve well in water. It can also be used for laundry starch, biodegradable plastics, adhesives, and paper products. The bond may result from the electrostatic force of attraction between oppositely charged ions as in ionic bonds; or through the sharing of electrons as in covalent bonds . In a covalent compound, the covalent bonds are involved where the mutual sharing of electrons that can hold all atoms or molecules together.
