Aluminum Atom Structure - Bohr Model Diagram Explained #16837 (License: Personal Use)

The diagram depicts a simplified Bohr model of a neutral aluminum atom, with the nucleus labeled "Al" at the center and three concentric circular orbits representing electron shells. The innermost shell holds 2 electrons, the middle shell holds 8, and the outermost shell contains 3 electrons-matching aluminum’s electron configuration of 1s² 2s² 2p⁶ 3s² 3p¹. This visual aids in understanding valence electrons and chemical reactivity.

Used in educational contexts-high school or introductory college chemistry-to teach atomic structure, electron configuration, and periodic trends. Matches user intent for learning or teaching how atoms are organized, especially for elements like aluminum with atomic number 13.
