Atomic Structure Diagram - Bohr Model with Protons, Neutrons & Electrons #3777408 (License: Personal Use)

This diagram depicts a simplified Bohr model of an atom, featuring a dense central nucleus composed of red spheres (protons) and blue spheres (neutrons), surrounded by three concentric circular orbits holding gray electron particles. Each shell holds a specific number of electrons-2 in the first, 8 in the second, and 8 in the third-reflecting the electron capacity rules for early elements. The image uses color coding and spatial arrangement to clarify atomic composition and electron configuration.

Commonly used in educational websites, science textbooks, and classroom presentations to teach basic atomic theory, electron shells, and subatomic particle roles; matches user intent for visual learning resources on chemistry fundamentals.
