Standard Electrode Potential -

If concentration of each species taking part in the electrode reaction is unity and further the reaction is carried out at 298 K, then the potential of each electrode is said to be the standard electrode potential.

more negative the value of the reduction  potential, stronger will be reducing agen, thus Iis strongest reducing agent more positive value of reduction potential shows good oxidising properties thus strongest oxidising agent is F2.
