CBSE Class 11-science Answered
Why are potassium and caesium, rather than lithium used in photoelectric cells?
Asked by Topperlearning User | 04 Jun, 2014, 01:23: PM
Expert Answer
Because of low ionization enthalpy of potassium and caesium as compared to lithium, they are able to lose their outermost electron when exposed or irradiated with light. This property makes caesium and potassium useful in photoelectric cells.
