Helium Atom Structure Diagram - Bohr Model Explained #93738 (License: Personal Use)

This diagram illustrates the simplified Bohr model of a helium atom, featuring a central nucleus composed of two red positively charged protons and two green neutral neutrons, encircled by a single electron shell holding two yellow negatively charged electrons. The model emphasizes stable electron configuration and atomic neutrality, making it ideal for introductory chemistry education. Though outdated for quantum accuracy, it remains widely used for foundational teaching.

Used in educational websites, science textbooks, and classroom presentations to introduce atomic structure; matches user intent for learning basic atomic models, especially for helium as the first noble gas.
