Atomic Structure Diagram - Bohr Model Visualization #3013668 (License: Personal Use)

This diagram illustrates the Bohr model of the atom, where electrons occupy fixed circular or elliptical orbits around a central nucleus. The three orange spheres represent electrons, while the intersecting black ellipses symbolize permitted energy levels or shells. Though simplified and superseded by quantum mechanical models, it remains a foundational teaching tool in chemistry and physics education.

Used in educational websites, textbooks, and science blogs to introduce atomic theory; matches user intent for visual learning, homework help, or curriculum-aligned content.
