Atomic Structure Diagram - Bohr Model Explained #16800 (License: Personal Use)

This diagram depicts the Bohr model of an atom, featuring a central nucleus containing four nucleons-two red spheres representing protons and two blue spheres for neutrons-surrounded by six gray electrons moving along elliptical orbits. The layered orbital paths demonstrate quantized energy levels, a foundational concept in early quantum theory. Though simplified, it remains widely used for introductory chemistry and physics instruction.

Used in educational websites, textbooks, and science blogs to explain atomic structure basics; matches user intent for learning fundamental particle physics or preparing classroom materials.
