ALKALI METALS Meaning and
Definition
-
Alkali metals refer to a group of chemical elements that belong to Group 1 of the periodic table. This group includes lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr). Alkali metals are highly reactive and reactive metals, characterized by their low melting and boiling points, as well as their soft and shiny appearance.
One defining characteristic of alkali metals is their ability to readily lose one electron in their outermost energy level to form a positive ion or cation, resulting in the formation of an ionic compound when they react with non-metallic elements. This property makes them highly reactive with water and air. When exposed to moisture or oxygen, alkali metals react vigorously, often leading to the production of hydrogen gas, heat, and sometimes fire. Due to their extreme reactivity, alkali metals are commonly stored under oil or inert gases to prevent their reaction with air or moisture.
Alkali metals possess several important properties that contribute to their diverse range of applications. For instance, they are extensively used in batteries, particularly lithium-ion batteries, which are widely used in portable electronic devices. They are also crucial in the field of medicine and nuclear research, as they have applications in nuclear reactors and positron emission tomography (PET) scans.
In summary, alkali metals are a group of reactive chemical elements that are characterized by their low melting and boiling points, soft texture, and high reactivity with water and air. With their distinct properties, alkali metals play a vital role in various fields, including energy storage, medicine, and nuclear research.

Etymology of ALKALI METALS
The word "alkali" comes from the Arabic word "al-qaly" or "al-qili", which means ash or alkali. These metals were originally referred to as "al-qaly metals" because they display similar properties to alkalis. Over time, the term evolved and became "alkali metals" to describe the group of elements that exhibit alkali-like characteristics such as high reactivity and the ability to form basic solutions when they react with water.
