Question

the three particles that make up atoms are

o positives, negatives, and electrons.

o protons, neutrons, and electrons.

o neutrons, isotopes, and electrons.

o protons, neutrons, and isotopes.

Explanation:

Atoms are composed of protons (positive - charged), neutrons (neutral), and electrons (negative - charged). Protons and neutrons are in the nucleus, and electrons orbit around the nucleus. Isotopes are different forms of an element with the same number of protons but different numbers of neutrons. So, the three fundamental particles that make up atoms are protons, neutrons, and electrons.

Answer:

protons, neutrons, and electrons.
