2Na + Br2 → 2NaBr
In this reaction, sodium atoms lose one valence electron each, becoming sodium ions (Na+). Bromine atoms gain one valence electron each, becoming bromide ions (Br-). The electrostatic attraction between the sodium and bromide ions forms an ionic bond, resulting in the formation of sodium bromide.
Sodium bromide is a white, crystalline solid that is highly soluble in water. It is commonly used as a source of bromide ions in various chemical and industrial applications.
