Atoms of lithium, sodium, and potassium are highly reactive due to their single valence electron. As a result, they readily form compounds with other elements to achieve a more stable electron configuration. This is why they are almost never found alone in nature.
Lithium, sodium, and potassium react vigorously with water to form hydroxides and release hydrogen gas. The reactivity increases as you go down the group from lithium to potassium, with potassium being the most reactive.
Iron is the odd one out because it is a transition metal, while lithium, potassium, and sodium are alkali metals.

Potassium is the most radioactive among lithium, sodium, and potassium. Potassium has a naturally occurring radioactive isotope, potassium-40, which is present in all potassium samples and contributes to its radioactivity.
While lithium and potassium are also alkali metals like sodium, they are more expensive and less commonly available in comparison to sodium. Sodium, being more abundant and cost-effective, is preferred for the preparation of sodium extract solution. Additionally, the reactivity of lithium and potassium is higher than sodium, making them more challenging to handle in this context.
The two most common alkali metals are sodium and potassium. They are found in many compounds and minerals, and are essential for various biological processes in living organisms.
