What are the differences between the photoelectric effect and Compton scattering in terms of their interactions with photons and electrons?

The photoelectric effect involves the ejection of electrons from a material when it absorbs photons, while Compton scattering is the process where photons collide with electrons, causing them to change direction and lose energy. The key difference is that in the photoelectric effect, electrons are ejected from the material, while in Compton scattering, electrons remain within the material but change their direction and energy.
