Which particles are contained in atoms?

Which particles are contained in atoms?

• A. Electrons, Protons, and Neutrons
• B. Only Electrons
• C. Only Protons
• D. Only Neutrons

Answer: (A)

Atoms contain three kinds of subatomic particles: electrons, protons, and neutrons. The nucleus at the center holds protons and neutrons, with protons carrying a positive charge and neutrons having no charge. Electrons surround the nucleus in regions called orbitals and are held in by the attraction to the positively charged nucleus. This arrangement gives atoms their structure and drives how they bond and interact with others. Most of the atom’s mass comes from the protons and neutrons in the nucleus, while electrons are much lighter but essential for chemistry. So all three types are part of an atom.
