# What occurs when electrons are added to the chlorine molecule, Cl_2?

Oct 14, 2016

You reduce the chlorine molecule.

#### Explanation:

As a non-metal, elemental chlorine tends to be oxidizing, i.e. it tends to gain electrons, and be reduced, i.e.

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

And thus we need to provide an electron source, i.e. typically a metal, for instance sodium, to make a salt:

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