This reaction is quite vigorous and releases a lot of energy, so it's not something you'd want to try at home. Here's a simplified explanation of what happens:
* Sodium (Na) is a very reactive metal. It wants to give away one electron to become more stable.
* Chlorine (Cl) is a very reactive nonmetal. It wants to gain one electron to become more stable.
* When they meet, the sodium atom readily gives its electron to the chlorine atom. This creates a strong ionic bond, forming sodium chloride.
The chemical equation for this reaction is:
2Na + Cl2 → 2NaCl
This reaction releases a lot of heat and light, making it a very exothermic reaction.
