WebFeb 1, 2024 · The alkali metals are lithium (Li), sodium (Na), potassium (K), rubidium (Rb), caesium (Cs), and francium (Fr). This group lies in the s-block of the periodic table, as all alkali metals have their outermost electron in an s-orbital. The alkali metals provide the best example of group trends in properties in the periodic table, with elements ... WebApr 5, 2024 · The alkali metals consist of six chemical elements: lithium, sodium, potassium, rubidium, cesium, and francium. They are located in group 1 of the periodic table and are the most reactive metals. They all have one valence electron in their outermost shell, making them highly reactive with water and other substances.
