Expert Answer:
When electromagnetic radiation strikes on the surface of alkali metals, they emit electrons. This is called the photoelectric effect.
This occurs as alkali metals have low ionization energies, which allows the electrons to be easily ejected when exposed to light. Among alkaline earth metals metals, Be and Mg has highest ionization energy and hence it can't show photoelectric effect to the some extent.
