question_answer 20)

The compound \[Ag{{F}_{2}}\] is unstable compound. However, if formed, the compound acts as a very strong oxidizing agent?

Answer:

\[A{{g}_{47}}\to 4{{d}^{10}},5{{s}^{1}}\] \[A{{g}^{+}}\to 4{{d}^{10}},5{{s}^{0}}\] \[A{{g}^{2+}}\to 4{{d}^{9}},5{{s}^{0}}\] 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. \[\underset{\begin{smallmatrix} Less \\ stable \end{smallmatrix}}{\mathop{A{{g}^{2+}}}}\,+{{e}^{-}}\to \underset{\begin{smallmatrix} More \\ stable \end{smallmatrix}}{\mathop{A{{g}^{+}}}}\,\]
