Atomic Structure Diagram - Bohr Model Visualization #115018 (License: Personal Use)

This diagram depicts the simplified Bohr model of an atom, with a glossy red sphere representing the nucleus (containing protons and neutrons) and eight gray spheres symbolizing electrons distributed across three concentric elliptical orbits. The blue orbital paths illustrate quantized energy levels, a foundational concept in early quantum theory. Though outdated for modern quantum mechanics, this visual remains widely used for introductory chemistry and physics education.

Commonly used in educational websites, textbooks, and classroom slides to introduce atomic theory; matches user intent for basic science explanations, student study aids, or STEM outreach content.
