C) electron and ion
D) proton and ion

Question

Quizplus · Accepted Answer

Electrons carry a negative charge, and protons carry a positive charge. These two types of particles are fundamental to the structure of atoms, which make up all known materials. Neutrons, also found in the nucleus of atoms, are neutral and do not carry an electric charge. Ions are atoms or molecules with a net electric charge due to the loss or gain of one or more electrons, not a basic particle of electric charge.
