Question

why, alkali metals are preferred in photoelectric effect ​

Answer 1

Answer:Alkali metals have lower ionization energy than their counterparts and hence have higher chance of emitting electrons when a radiation falls on them. So they are used in photoelectric cells so that they easily emit electron when energy containing photons in sunlight strikes them.
