This results directly from the Octet rule. Write the electronic configurations of these atoms/ions - you will see that Cl- and Na+ have 8 electrons each in the valence shell. This is the magic number needed to maximize the stability of the atom/ion (ie : make the total potential energy of the system = sum of all electron-nucleus interaction energies + electron-electron interaction energies as negative as possible).ghallya said:

Chlorine (Cl) is more active than its negatively charged counterpart, Cl-, because it has one less electron in its outermost energy level. This makes it more reactive and likely to form chemical bonds with other atoms.
In addition to having one less electron, Cl also has a smaller atomic radius compared to Cl-. This means that the outermost electrons are held more tightly and are more available for chemical reactions. Furthermore, Cl has a higher electronegativity, meaning it has a stronger attraction for electrons, making it more reactive.
The atomic structure of Cl, specifically its outermost energy level, plays a crucial role in its reactivity. With only 7 electrons in its outer shell, Cl is one electron short of achieving a stable octet. This drives its reactivity as it seeks to gain or lose one electron to reach a more stable state.
The activity of Cl, or its tendency to react with other substances, is directly related to its chemical properties. This is because the reactivity of an element determines the types of chemical bonds it can form and the types of compounds it can create. As such, Cl's high reactivity makes it a key component in a wide range of chemical reactions and compounds.
Yes, the high reactivity of Cl has numerous practical applications in various industries. For example, it is commonly used to purify water and treat wastewater due to its ability to react with and eliminate harmful bacteria and contaminants. Cl is also used in the production of plastics, solvents, and many other products. Additionally, it is an essential element in the production of medicines and agricultural chemicals.
