The elements in the first group of the periodic table are known as **alkali metals**. This group includes lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr). Alkali metals are characterized by their high reactivity, particularly with water, and they have a single electron in their outermost shell, which they readily lose to form positive ions.
