* Electron Configuration: Both potassium and sodium have a single electron in their outermost shell (valence electron). This single electron is relatively loosely held and easily lost, making them highly reactive.
* Tendency to Form Cations: The loss of this single valence electron results in the formation of a +1 ion (cation). Both potassium and sodium readily form cations, which is why they are highly reactive with nonmetals.
* Similar Reactivity: Due to the similar electron configuration and ease of forming cations, both elements react vigorously with water, oxygen, and halogens. Their reactions often release significant amounts of energy.
In summary:
* Group 1 (Alkali Metals): All elements in this group share the characteristic of having one valence electron, leading to similar chemical behavior.
* Reactivity: The tendency to lose their valence electron makes them highly reactive, with properties including:
* Vigorous reaction with water
* Formation of ionic compounds with nonmetals
* Ease of oxidation
