Web28 mrt. 2024 · Ions are formed when atoms gain or lose charge to achieve a noble gas configuration. Size: Molecule size depends on the size of the atoms or ions involved in the bond formation. Anions are more significant than parent molecules, and cations are more minor than parent molecules. Stability: Molecules are more stable than ions. Web25 jan. 2024 · In any crystal, the constituent ions of the ionic compound are held together by electrostatic forces of attraction. The stronger the forces of attraction, the higher is the lattice energy and the more stable is the compound. This electrostatic force of attraction is determined by Coulomb’s Law.
