WebIon size: the smaller the anion, the greater the concentration of charge on the surface of the ion, leading to stronger forces of attraction with a given cation. Hydration energy: the smaller an ion, the greater the attraction for the water molecules surrounding (solvating) it. WebIons are atoms that gain or lose electrons. When an atom receives or loses an outermost electron, the ionic radius describes the change in size (i.e., radius) (s). When an atom …

Web23 mrt. 2024 · Ionic charge: When the atom loses or gains one or more electrons, the electric charge is generated (and an ion is formed). This electric charge generated on the ion is known as Ionic charge. When atoms gain electron/s, the negatively charged ion is formed, and when the atoms lose electron/s, the positively charged ion is formed.
