Aluminum Atom Structure - Bohr Model Diagram Explained #93745 (License: Personal Use)

The diagram depicts the simplified planetary model of an aluminum atom, 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 atomic number 13 and group 13 position in the periodic table. This representation helps students grasp basic atomic configuration and chemical reactivity.

Used in chemistry education materials, textbooks, and science websites to explain atomic structure, electron configuration, and periodic trends; matches user intent for learning or teaching foundational atomic theory.
