Photoelectric effect

Why does the photoelectric effect mention the emission of electrons but then the gold leaf experiment which is supposed to demonstrate it mentions emission of photoelectrons instead?

Just a naming issue, not physics. An electron ejected by the photoelectric effect is still an electron, but we can also call it a photoelectron as that is how it got liberated from a surface.

Both photoelectric effect and the gold leaf show that electrons are ejected when the photon has enough quantized energy. This ejection leads to energized photoelectrons.
There is just a misunderstanding in the terms, no more.
