What holds together anions?

Anions are held together by ionic bonds when they interact with cations, forming ionic compounds. The electrostatic attraction between the negatively charged anions and positively charged cations creates a stable structure. In covalent compounds, anions may also share electrons with cations, resulting in molecular bonds that further stabilize the arrangement. Overall, the combination of electrostatic forces and shared electron pairs contributes to the cohesion of anionic structures.
