| $(iii)$ An atom may or may not have an independent existence. | $(iii)$ An ion does not has an independent existence. |
| $(iv)$ In an atom, the outermost orbit may be unstable. Eg. $: Na$ (Sodium), $K$ (Potassium) $Na (2, 8, 1), K (2, 8, 8, 1)$ | $(iv)$ In an ion, the outermost orbit is stable. Eg.$: Na^+$ (sodium ion), $K^+$ (potassium ion) $Na^+ (2, 8), K^+ (2, 8, 8)$ |
