Name a dipositive metal ion with configuration:\[1{{s}^{2}}2{{s}^{2}}\,2{{p}^{6}}3{{s}^{2}}\,3{{p}^{6}}\,3{{d}^{5}}\]

Answer:

                The configuration of ion\[({{M}^{2+}}):1{{s}^{2}}\,2{{s}^{2}}\underset{\downarrow }{\mathop{\cdot 2{{p}^{6}}}}\,\underset{+\,2{{e}^{-}}}{\mathop{\,3{{s}^{2}}}}\,3{{p}^{6}}\,3{{d}^{5}}.\] The configuration of atom\[(M):1{{s}^{2}}\cdot \,2{{s}^{2}}\underset{{}}{\mathop{2{{p}^{6}}}}\,\underset{{}}{\mathop{\,3{{s}^{2}}}}\,3{{p}^{6}}4{{s}^{2}}\,3{{d}^{5}}\] The atom represents manganese (Mn) and the dipositive ion is \[M{{n}^{2+}}\] ion.
