What happens when a sodium atom and a chlorine atom exchange an electron?

1 Answer

Sep 16, 2016

A redox reaction that results in salt formation.

Explanation:

$Oxidation:$ $"Oxidation:"$

$N a (g) \to N a^{+} + e^{-}$ $Na(g) rarr Na^+ + e^-$

$Reduction:$ $"Reduction:"$

$\frac{1}{2} C l_{2} (g) + e^{-} \to C l^{-}$ $1/2Cl_2(g) + e^(-) rarr Cl^-$

Add these equations together:

$N a (g) + \frac{1}{2} C l_{2} (g) \to N a^{+} C l^{-} (s)$ $Na(g) + 1/2Cl_2(g) rarr Na^(+) Cl^(-)(s)$
