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

Sep 16, 2016

A redox reaction that results in salt formation.

#### Explanation:

$\text{Oxidation:}$

$N a \left(g\right) \rightarrow N {a}^{+} + {e}^{-}$

$\text{Reduction:}$

$\frac{1}{2} C {l}_{2} \left(g\right) + {e}^{-} \rightarrow C {l}^{-}$

$N a \left(g\right) + \frac{1}{2} C {l}_{2} \left(g\right) \rightarrow N {a}^{+} C {l}^{-} \left(s\right)$
