Alkali metals react vigorously with chlorine to form metal chlorides. Lithium reacts with chlorine gas to form lithium chloride according to the chemical equation 2Li (s) + Cl2 (g) → 2LiCl (s). Sodium also reacts with chlorine gas in a similar reaction to form sodium chloride, represented by the equation 2Na (s) + Cl2 (g) → 2NaCl (s).

2. How do alkali metals react with chlorine?
Alkali metals burst into flames when heated and added to
chlorine. They form metal chlorides.
alkali metal + chlorine alkali metal chloride
The word and chemical equations for the reaction between
lithium and chlorine are:
lithium + chlorine lithium chloride
2Li (s) + Cl2 (g) 2LiCl (s)
What are the word and chemical equations for the reaction
that produces sodium chloride?
sodium + chlorine sodium chloride
2Na (s) + Cl2 (g) 2NaCl (s)
