The resulting attraction between these oppositely charged ions is known as an ionic bond . This "Coulombic interaction" is highly exothermic, meaning it releases a significant amount of energy—often visible in laboratory demonstrations as a bright orange or red glow. This release of energy is the driving force that stabilizes the compound, creating a substance with properties entirely different from its parent elements.
) , a pungent yellow-green gas. The formation of the bond is driven by the octet rule, where atoms seek a stable electron configuration. Sodium, having one valence electron, donates it to chlorine, which requires one electron to complete its outer shell. This electron transfer transforms the neutral atoms into ions: a positively charged sodium cation ( Na+cap N a raised to the positive power ) and a negatively charged chloride anion ( Cl−cap C l raised to the negative power NACL 030_ANI_01.mp4
