Energy Emission: Electrons vs Protons

[scientifico]

Hello, I read that if an high energy electron impact with atoms some electron of the atoms can be emitted, does that happen with every high energy particle?
For example, using an high energy proton instead of electron, will the opposite charges attract and reduce a bit the energy of the emitted electron?

Thank you!

The "impact" with an atom is usually an electromagnetic interaction ... sure, any particle can do this. Here's an example experiment using your example - protons:
Energy and angular distributions of electrons emitted and ions recoiled in proton-impact ionization of helium atoms

The resulting kinetic energies depend on the dynamics of the interaction.
There is no special reason that the emitted electron in a proton collision should be any less than for an electron collision.

I mean if protons and electrons attract themself, will this "attraction" energy be subtracted from the kinetic energy of the impact?
If not, where does the attraction proton-electron came from and why it regards only that two praticles?

Thank you!

Collision of a charged particle with an atom is much more complicated than you seem to think. Please see:
