Atomic Structure Diagram - Nucleus with Protons, Neutrons, and Electrons #3013634 (License: Personal Use)

This diagram depicts a simplified Bohr model of an atom, where the nucleus contains alternating blue spheres (protons) and green spheres (neutrons), while eight red spheres represent electrons moving along elliptical orbits. The clean, colorful design emphasizes fundamental particle roles and orbital arrangement, making it ideal for introductory chemistry or physics instruction. It avoids quantum complexity to focus on core atomic concepts.

Used in educational websites, K-12 science curricula, and introductory college physics/chemistry pages to explain atomic composition and historical atomic models. Matches user intent for visual learning, homework help, or quick reference.
