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

Compton scattering and the photoelectric effect are both ways that X-rays interact with matter. The main difference is that in Compton scattering, X-rays collide with electrons in the material and lose energy, causing them to change direction. In the photoelectric effect, X-rays are absorbed by electrons in the material, causing them to be ejected from their atoms. This results in the X-rays losing all of their energy.
