Answer:
Examples of metals are copper, sodium which exhibit the photoelectric effect.
Explanation:
Alkali metal is generally used for exhibiting the photoelectric effect. Alkali metals have low threshold energy. So when they are heated by the emit electron and the amount of energy needed for this is very low.
Other metals have high threshold energy, therefore, they require a large amount of heat to eject electrons. So alkali metals are the element of choice to be used in the photoelectric effect.
