The compound $AgF_2$ is an unstable compound. However,if formed,the compound acts as a very strong oxidizing agent. Why?
(N/A) $AgF_2$ contains $Ag$ in the $+2$ oxidation state.
Since $+2$ is an unstable oxidation state for $Ag$,it has a strong tendency to gain an electron to return to the more stable $+1$ oxidation state $(Ag^{2+} + e^- \rightarrow Ag^+)$.
Because it readily gains an electron,it acts as a powerful oxidizing agent.
