Atomic Structure Icon - Science & Education Symbol #3506698 (License: Personal Use)

This monochrome line-art illustration depicts a simplified atomic model with a central nucleus containing protons and neutrons, surrounded by three elliptical electron orbits. Each orbit holds a single electron represented as a circle with a small internal detail. The design follows the iconic planetary model often used in educational contexts to convey basic atomic theory.

Commonly used on educational platforms, science blogs, university pages, or infographics explaining chemistry and physics fundamentals; serves users seeking visual metaphors for atomic theory, quantum basics, or STEM branding.
