Question

the three particles that make up atoms are *
neutrons, isotopes, and electrons
positives, negatives, and neutrals
protons, neutrons, and isotopes
protons, neutrons, and electrons

Explanation:

Atoms are made up of protons (positively - charged), neutrons (neutral), and electrons (negatively - charged). Isotopes are different forms of an element with the same number of protons but different numbers of neutrons. Positives, negatives, and neutrals is an incorrect description as protons are positive, electrons are negative, and neutrons are neutral. Protons, neutrons, and isotopes is wrong because isotopes are not sub - atomic particles. Neutrons, isotopes, and electrons is also wrong as isotopes are not sub - atomic particles.

Answer:

Protons, neutrons, and electrons.
