why can caesium be used in photoelectric cell while Lithium not?
Cs can lose it electron easily than Li .
due to the larger size os CS than Li, ionization enthalphy of Cs is lesser than Li.
so for photoelectric cell ,the electron should release when the light is present.
so Cs is used Li is not used .(Li will not lose electron easily)
