Sodium and Chlorine Electron Transfer Diagram - Ionic Bond Formation #93755 (License: Personal Use)

The diagram shows a neutral sodium atom with 11 protons and 12 neutrons in its nucleus, and 11 electrons arranged in shells (2, 8, 1); it donates its single valence electron to chlorine. Chlorine, with 17 protons and 18-20 neutrons, initially has 17 electrons (2, 8, 7) and gains that electron to achieve a stable octet (2, 8, 8), becoming Cl⁻, while sodium becomes Na⁺.

Used in educational chemistry content-textbooks, lesson slides, or online tutorials-to explain ionic bonding, electron configuration, and ion formation. Matches user intent for visual learning of basic atomic interactions.
