Question

is photoelectric effect can be seen in alkaline earth metals?​

Answer 1

Answer:

yes photo electric effect is seen in alkaline earth metals when the photons are passed on the metals the electrons are ejected out ....

photons observed by metals is proportional to no.of ejected out electrons ...it is introduced by Hertz in 1887

Answer 2

Answer:

When electromagnetic radiation strikes on the surface of alkaline metals,the emict electrons.This is called the photoelectric effect.

This occurs as alkaline metals have low ionization energies,which allows the electrons to be easily ejected when exposed to light. Among alkalines the earth metals, Be and Mg has highest ionization energy and hence it can't show photoelectric effect to the some extent.
