Atomic Structure Explained: Protons, Neutrons, and Electrons #3902688 (License: Personal Use)

This educational illustration depicts a classic planetary atomic model with a central nucleus composed of orange protons and gray neutrons, encircled by blue electrons moving along elliptical orbits. The color-coded legend clarifies particle identities and charges: + for protons, neutral for neutrons, and - for electrons. Though stylized (not quantum-accurate), it effectively conveys foundational atomic composition for introductory science learning.

Used in K-12 science curricula, educational websites, and STEM outreach materials to introduce atomic theory; matches user intent for basic chemistry/physics explanations or visual study aids.
