Alkali metals

 Alkali metals have many properties, including:

Softness: Alkali metals are soft and can be cut with a butter knife. 

Low density: Alkali metals are less dense than other metals. 

Low melting point: Alkali metals have low melting points compared to other metals. 

High reactivity: Alkali metals are highly reactive and must be stored in special containers or solutions. 

Low ionization energy: Alkali metals have the lowest first ionization energies of all elements. 

Low electronegativity: Alkali metals have low electronegativity. 

Good conductors: Alkali metals are good conductors of heat and electricity. 

Shiny: Alkali metals are shiny and silvery white in color. 

Oxidize easily: Alkali metals oxidize easily in water, releasing hydrogen gas. 

React with halogens: Alkali metals react easily with halogens. 

Explanation

Alkali Metals - Properties, Electronic Configuration ...

Alkali metals are in group 1 of the periodic table. They are highly reactive because they have one electron in their outermost electron layer. This makes it easy for them to lose their outermost electron and become a +1 ion. 

The alkali metals are lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr). They are located in the first column, or Group 1, of the periodic table. 

Explanation

Alkali metals are soft, shiny metals with low melting points. 

They are named for their reaction with water to form alkaline metal hydroxides, which have a pH above 7. 

Alkali metals are useful in many applications, including batteries, medical imaging, and atomic clocks. 

Francium is the rarest alkali metal and is used in research and cancer diagnosis.
