All of the members of the alkali metal family have one valence electron (in their outermost s orbital). Therefore, they are strong reducing agents and tend to react in such a way as to lose this electron in order to obtain a more stable electron configuration.

Alkali metals are metallic, and therefore all have a Silvery-grey appearance.

(Alkali metals are stored usually in oil, and when they are removed from the oil they usually have a dull grey colour because of the minor reaction that the metal has with the oil. Only the outer most part of the alkali metal will be this colour, and when cut, the middle of the metal will be exposed, and the silvery-grey appearance can be observed.)
