aka salt bridge, a strong noncovalent attraction between 2 charged molecules (ions), a negatively-charged on (anion) and a positively-charged one (cation). There is no electron sharing involved, but they stick together because they like each other’s opposite charge. Because ionic bonds involve fully-charged molecules, they’re stronger than noncovalent interactions like van der Waal’s interactions which only involve attractions between temporary charges. But, because they don’t involve electron sharing, they’re weaker than covalent bonds.
