Atoms are composed of protons, neutrons, and

Electrons. I know because on talking tom and friends, talking ben made a scientific joke about protons and electrons. The word protons reminded me of that, so that's how I know it. Nothing to do with school. The end.

Electrons is your answer ,because every atom has to have those three(Protons,Neutrons,And Electrons)I know because we just finished semester 1 and we learned about that stuff. I hope this helps and you got some information out of this. Have a good day!
