Helium Atom Diagram - Bohr Model Visualization for Science Education #3333444 (License: Personal Use)

This diagram represents a simplified helium atom in the Bohr model format, with a nucleus containing one red sphere marked with a plus sign (proton) and one purple sphere (neutron), and a single blue electron marked with a minus sign orbiting outside the nucleus along a circular path. Though not to scale, it conveys core concepts of atomic composition and electron shells for introductory chemistry education. The transparent background allows easy integration into digital learning materials.

Used in K-12 science curricula, online tutorials, and educational websites to explain atomic structure, subatomic particles, and early quantum models. Matches user intent for visual learning aids, homework help, or classroom presentation assets.
