• # question_answer 20) The compound $Ag{{F}_{2}}$ is unstable compound. However, if formed, the compound acts as a very strong oxidizing agent?

$A{{g}_{47}}\to 4{{d}^{10}},5{{s}^{1}}$ $A{{g}^{+}}\to 4{{d}^{10}},5{{s}^{0}}$ $A{{g}^{2+}}\to 4{{d}^{9}},5{{s}^{0}}$ Configuration shows that $A{{g}^{+}}$ is more stable than$A{{g}^{2+}}$, thus $A{{g}^{2+}}$ change to $A{{g}^{+}}$ and it acts as oxidising agent. $\underset{\begin{smallmatrix} Less \\ stable \end{smallmatrix}}{\mathop{A{{g}^{2+}}}}\,+{{e}^{-}}\to \underset{\begin{smallmatrix} More \\ stable \end{smallmatrix}}{\mathop{A{{g}^{+}}}}\,$
