We know that Alkali metals are photosensitive and readily exhibit photoelectric effect, suppose you are given 4 Alkali metals Li, Na, K and Cs – determine which metal would be the best for showing photoelectric effect. If the values of work functions of these 4 metals are 1.9eV, 2.9eV, 2.3eV, 2.4eV in no specific order. Map the metals with their values of work functions.
