The correct answer to this question is Protons, neutrons, and electrons. These parts all have their own charges. Protons have a positive charge. They are often indicated with a plus sign (+). Neutrons don't have a charge.
Electrons have a negative charge and are often indicated with a minus sign (-). Protons and neutrons are always together. Meanwhile, the electrons are orbiting the nucleus. Atoms are very small particles that makeup elements.
Each element has protons, and they are different numbers depending on the element. In total, there are over 100 types of atoms. Out of those, 92 are natural, while the rest are in labs.
