Formation of Sodium Chloride

2Na + Cl2 → 2NaCl

개요

Sodium metal reacts vigorously with chlorine gas to form sodium chloride, common table salt. This is a classic example of an ionic compound formation where a metal transfers electrons to a nonmetal. The reaction is highly exothermic, producing a bright yellow flame.
