Aluminum Atom Structure - Bohr Model Diagram Explained #8406 (License: Personal Use)

This diagram depicts the simplified Bohr model of an aluminum atom (symbol Al, atomic number 13), with a central nucleus labeled “Al” surrounded by three concentric electron shells. The innermost shell holds 2 electrons, the second holds 8, and the outermost (valence) shell contains 3 electrons-reflecting aluminum’s electron configuration of 1s² 2s² 2p⁶ 3s² 3p¹. The model is ideal for introductory chemistry education to explain periodic trends and metallic bonding behavior.

Used in educational websites, science textbooks, and classroom presentations to teach atomic theory, electron configuration, and properties of metals; targets students, teachers, and learners seeking foundational chemistry visuals.
