Alkali metals take up the leftmost side of the periodic table. The group 1 elements consist of elements:
Lithium (Li)
Sodium (Na)
Potassium (K)
Rubidium (Rb)
Caesium (Cs)
Francium (Fr)
As the alkali metals have only 1 electron in their valence shell, they readily lose it, making them count among the most reactive elements on earth. Thus, they are highly electropositive metals. They are called alkali metals because they form strongly alkaline hydroxides with water.
