Argon Atom Structure - Bohr Model Diagram Explained #3536555 (License: Personal Use)

This diagram depicts the Bohr model of a neutral argon atom (atomic number 18), featuring a pink nucleus labeled “Ar” surrounded by three circular electron shells. The innermost shell holds 2 electrons, the second holds 8, and the outermost (valence) shell contains 8 electrons-confirming argon’s status as a noble gas with a full octet. Electrons are shown as blue dots evenly spaced along each orbit.

Commonly used in educational resources like high school or introductory college chemistry pages to teach atomic structure, electron configuration, and periodic table trends; matches user intent for visual learning and quick reference on noble gases.
