Notation of hydrogen $$\ce{e- + H2O -&gt; [H$\cdot$] + HO-}$$

I was a little confused on the notation of the hydrogen in brackets ([H]) in the product side of the reaction. Why is there a dot next to it and what does it mean? Is it saying Hydrogen gas?

Also, what will be the reduction potential of this reaction?
The notation $\ce{H^.}$ refers to the hydrogen radical (a hydrogen atom). The dot represents the unpaired valence electron. 

An equivalent notation for the reaction would be 

$$\ce{e- + H2O -&gt; H + OH-}$$

However, adding the dot emphasizes the fate of the electron on the reactant side.
