Alkali Metals

Alkali metals refer to a group of chemical elements in group 1 of the periodic table, characterized by their similar properties and reactivity. This group includes lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr). Alkali metals are known for having a single electron in their outermost shell, which they readily lose to form positive ions with a charge of +1. This gives them a strong tendency to react with nonmetals, particularly halogens, and water, resulting in the formation of hydroxides and the release of hydrogen gas.They are typically soft, silvery-white metals that are less dense than most other metals and have relatively low melting and boiling points. Alkali metals are highly reactive, especially with water, and must be stored under oil or in an inert atmosphere to prevent reaction with moisture in the air. Due to their reactivity, they do not occur freely in nature but are commonly found in various minerals and compounds. Their reactivity and unique properties make them important in various chemical processes and applications in fields such as chemistry, materials science, and medicine.
