How many alkali metals are on the periodic table?

6: lithium(Li) ,sodium(Na) , potassium(K) , rubidium (Rb) , cesium (Cs) and Francium(Fr). Practically,only the first five can be termed alkali metals,because there is not enough Francium in the planet to examine its characteristics. Of course, the electron structure of the atom of Francium "proposes" an alkali metal.
