1. Electronegativity: Chlorine is much more electronegative than sodium. This means chlorine has a stronger attraction for electrons.
2. Electron Transfer: Sodium, with only one electron in its outer shell, easily loses this electron to achieve a stable, filled outer shell. Chlorine, needing one more electron to fill its outer shell, readily accepts the electron from sodium.
3. Ion Formation: Sodium loses an electron, becoming a positively charged ion (Na+). Chlorine gains an electron, becoming a negatively charged ion (Cl-).
4. Electrostatic Attraction: The opposite charges of the sodium and chlorine ions attract each other strongly, forming an ionic bond.
5. Crystal Lattice: Many sodium and chlorine ions arrange themselves in a regular, repeating pattern called a crystal lattice, creating a solid, crystalline structure.
In summary:
* Sodium (Na) and chlorine (Cl) form an ionic bond.
* Sodium loses an electron to become a positively charged ion (Na+).
* Chlorine gains an electron to become a negatively charged ion (Cl-).
* The opposite charges of the ions attract each other, forming the ionic bond.
* The resulting compound is sodium chloride (NaCl).
