What 3 parts make up an atom?

The structure of an atom is primarily composed of three fundamental particles: protons, neutrons, and electrons. Protons are positively charged particles located in the nucleus at the center of the atom, while neutrons, which have no charge, exist alongside protons in the nucleus. Electrons are negatively charged particles that orbit around the nucleus in various energy levels or shells.

This foundational knowledge is critical in understanding chemical behavior and the principles of electrical engineering and physics, particularly how atoms interact to form bonds and conduct electricity. Protons and neutrons contribute to the atomic mass and stability of the atom, while electrons are essential for chemical reactions and the flow of electric current.

The chosen answer accurately identifies these three particles, reflecting the accepted scientific understanding of atomic structure.
