Aluminum Atom Structure - Bohr Model Diagram Explained #1999597 (License: Personal Use)

This diagram depicts the Bohr model of a neutral aluminum atom (Al, atomic number 13), with a central nucleus labeled “Al” surrounded by three concentric electron shells. The innermost (K) shell holds 2 electrons, the middle (L) shell holds 8, and the outermost (M) shell contains 3 valence electrons-consistent with aluminum’s position in group 13 of the periodic table. The representation is idealized for teaching foundational atomic theory.

Used in chemistry education materials, textbooks, and online learning platforms to explain atomic structure, electron configuration, and periodic trends; targets students and educators seeking visual reinforcement of basic atomic models.
