Alkali metals are a group of elements in the periodic table that includes lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr). They are located in Group 1 of the periodic table and are known for their high reactivity and tendency to form alkali metal compounds.
Alkali metals have several distinctive properties that make them unique from other elements. They are soft, highly reactive metals with low melting and boiling points. They are also excellent conductors of heat and electricity, making them useful in various applications, such as batteries and heat exchangers.
In their pure form, alkali metals are silvery-white and highly reactive, and they react with water to form hydroxides and hydrogen gas. They also react readily with other elements to form compounds, and many of these compounds have important industrial, medical, and agricultural applications.
Alkali metals are abundant in the Earth’s crust and are widely used in a variety of industries, including chemical manufacturing, electronics, and pharmaceuticals. Despite their high reactivity, alkali metals have a variety of applications that make them valuable in many different fields, and they are likely to continue to be important in the future.
