Atomic Structure Diagram: Electron Shells and Nucleus Visualization #1999602 (License: Personal Use)

The upper sphere depicts a simplified Bohr-style atom with multiple electrons (golden spheres with minus signs) arranged in discrete concentric shells within a pink electron cloud. The lower yellow sphere represents the nucleus-centered model, highlighting a single proton (red sphere with plus sign) at the core, intersected by black lines denoting quantized energy levels or orbital planes. Both visuals emphasize foundational concepts in atomic physics and quantum theory.

Used in educational web pages, science textbooks, or introductory chemistry courses to explain atomic models, electron configuration, and nuclear composition; targets students and educators seeking visual reinforcement of theoretical concepts.
