Question

CGM metal is used in photoelectric celll ....give reason

Answer 1

One more thing--> Alkali metals used to have low ionisation enthalpies and therefore, the electrons are easily ejected when exposed to light. Among alkali metals, cesium has lowest ionisation enthalpy and hence it can show photoelectric effect to the maximum extent and therefore preffered in photoelectric cell.

Answer 2

Hay mate here is your answer ✌❤☺
