Atomic Structure Diagram - Bohr Model Visualization #191556 (License: Personal Use)

This diagram depicts the Bohr atomic model, where a dense nucleus-containing red protons and yellow neutrons-is surrounded by concentric elliptical orbits occupied by blue electrons. The structure visually represents quantized energy levels and electron transitions, foundational to early quantum theory. It remains widely used in introductory chemistry and physics curricula.

Used in educational websites, textbooks, and science blogs to explain atomic theory basics; targets students, teachers, and curious learners seeking visual understanding of atomic composition and electron configuration.
