A) \[4s\] and \[3d\] have the same energy
B) \[4s\] has a higher energy than \[3d\]
C) \[4{{s}^{1}}\] is more stable than \[4{{s}^{2}}\]
D) \[4{{s}^{1}}3{{d}^{5}}\] half-filled is more stable than \[4{{s}^{2}}3{{d}^{4}}\]
Correct Answer: D
Solution :
\[Cr\] has \[\left[ Ar \right]\,4{{s}^{1}}3{{d}^{5}}\] electronic configuration because half filled orbital are more stable than other orbitals.You need to login to perform this action.
