ANSWER :-
✨ PHOTOELECTRIC EFFECT ✨
✴ When a particular frequency of light get a strike on over metal surface electron get ejected from metal.
✴ electron is known as photoelectron and this phenomena is known as Photoelectric effect.
✴ in periodic table top to bottom ionisation energy decreases so Photoelectric effect increases.
⚡ order of Photoelectric effect ⚡
Li < Na < K < Rb < Cs
Be < Mg < Ca < Sr < Ba
✴'Be' does not show photoelectric effect.
