Aluminum Atom Structure - Bohr Model Diagram Explained #3902661 (License: Personal Use)

This diagram depicts the Bohr model of a neutral aluminum atom (symbol Al, atomic number 13), featuring a central nucleus surrounded by three concentric electron shells. The innermost (K) shell holds 2 electrons, the second (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 arrangement highlights its tendency to lose three electrons and form Al³⁺ ions.

Used in educational chemistry resources, textbooks, and online learning platforms to teach atomic theory, electron configuration, and periodic trends; ideal for students studying introductory atomic structure or preparing for standardized science exams.
