Alkali metals are a group of elements on the periodic table found in Group 1. They include elements such as lithium, sodium, potassium, and rubidium. Alkali metals are known for their low density, high reactivity, and tendency to lose one electron during chemical reactions.

Alkali Metals Ionization Energy: Alkali metals have low ionization energies because they readily lose one electron.
Alkali Metals Electronegativity: Alkali metals have very low electronegativities because they don't attract electrons strongly in chemical bonds.
Alkali Metals Reactivity: Alkali metals are highly reactive due to their strong desire to lose one electron and achieve a stable outermost energy level.
