You are absolutely correct! Chlorine gas (Cl₂) reacts vigorously with sodium metal (Na) to produce sodium chloride (NaCl), a common table salt.

Here's the balanced chemical equation:

2 Na (s) + Cl₂ (g) → 2 NaCl (s)

Explanation:

* Sodium (Na) is a highly reactive alkali metal.

* Chlorine (Cl₂) is a greenish-yellow gas, also highly reactive.

* When these two elements come together, they undergo a violent exothermic reaction, releasing a significant amount of heat and light.

* The reaction forms sodium chloride (NaCl), a white crystalline solid, commonly known as table salt.

Safety Note: This reaction is very dangerous to perform without proper safety equipment and expertise. The heat and light produced can be intense, and chlorine gas is toxic.
