    The stable  electronic configuration of chromium is

    A) \[3{{d}^{6}},4{{s}^{1}}\]

    B) \[3{{d}^{5}},4{{s}^{2}}\]

    C)  \[3{{d}^{5}},4{{s}^{1}}\]

    D) \[3{{d}^{6}},4{{s}^{0}}\]

    Correct Answer: C

    Solution :

     \[Cr(24)=1{{s}^{2}},2{{s}^{2}}2{{p}^{6}},3{{s}^{2}}3{{p}^{6}}3{{d}^{5}},4{{s}^{1}}\] So, stable electronic configuration is \[3{{d}^{5}},4{{s}^{1}}\]
