Because they have one valence electron each.

The Alkali Metals are the first column of the periodic table, except for Hydrogen.
the alkali metals
Hydrogen is a non-metal; it's in group VII
The alkali metals are group 1, also known as group 1A.
This is the first column in the Periodic Table. There are six metals that are "Alkali Metals" and six that are "Alkali Earth Metals". The Alkali metals are:LithiumSodiumPotassiumRubidiumCaesiumFranciumThese metals get more reactive as you go down the list...Hope I helped :D
The elements located in the first column, group IA on the periodic table, are called alkali metals.
Yes,alkali metals belongs to first group.Formerly known as Group IA.They are very reactive.
alkali metals, alkali earth metals, and some transition metals.. that is on the left side if you divide the periodic table in two.
