Why alkali metals is photosensitive?
Alkali metals are photosensitive because they have low ionization energies. When they absorb light, they can easily lose an electron and undergo a photoelectric effect, leading to photoemission. This property makes them reactive in the presence of light.

Is alkali the only earth metal?
No, alkali metals are not the only earth metals. Earth metals include both alkali metals and alkaline earth metals. Alkaline earth metals are a group of elements in the periodic table that are chemically similar to, but less reactive than, alkali metals.
