A) \[[Ne]3{{s}^{2}}3{{p}^{6}}3{{d}^{4}},4{{s}^{2}}\]
B) \[[Ne]3{{s}^{2}}3{{p}^{6}}3{{d}^{5}},4{{s}^{1}}\]
C) \[[Ne]3{{s}^{2}}3{{p}^{6}}3{{d}^{6}},4{{s}^{1}}\]
D) \[[Ne]3{{s}^{2}}3{{p}^{5}}3{{d}^{5}},4{{s}^{2}}\]
Correct Answer: B
Solution :
Not Available \[Cr(Z=24)\] has electronic configuration \[1{{s}^{2}}2{{s}^{2}}2{{p}^{6}}3{{s}^{2}}3{{p}^{6}}3{{d}^{5}}4{{s}^{1}}\] (\[\because \] half filled d orbital is more stable than incompletely filled d orbital)
