A) \[C{{u}^{+}}\]
B) \[F{{e}^{+}}\]
C) \[F{{e}^{2+}}\]
D) \[F{{e}^{3+}}\]
Correct Answer: D
Solution :
\[F{{e}^{3+}}\]electronic configuration \[3{{s}^{2}}3{{p}^{6}}3{{d}^{5}},\] has half-filled d-orbital is more stable than \[C{{u}^{+}},F{{e}^{+}}\] arid q\[F{{e}^{2+}}\] . \[C{{u}^{+}}\] electronic configuration \[3{{s}^{2}}3{{p}^{6}}3{{d}^{10}}\] although having fully-filled 3rd shell is less stable because nuclear charge (29 protons) on \[Cu\] is not sufficient enough to hold 28 electrons.
