Atomic Structure Diagram - Bohr Model Visualization #3518250 (License: Personal Use)

This diagram depicts a simplified Bohr model of an atom, featuring a nucleus composed of red spheres (protons) and blue spheres (neutrons), surrounded by three black electrons moving along defined elliptical orbits. The illustration emphasizes early 20th-century quantum theory concepts, though modern quantum mechanics replaces fixed orbits with probability clouds. It remains widely used for introductory chemistry and physics education.

Commonly used in educational websites, textbooks, and classroom presentations to introduce atomic structure; matches user intent for basic science learning, homework help, or visual reference for atomic models.
