A) 11
B) 15
C) 14
D) 13
Correct Answer: D
Solution :
K L M N M(26) \[1{{s}^{2}}\], \[2{{s}^{2}}2{{p}^{6}}\], \[3{{s}^{2}}3{{p}^{6}}3{{d}^{6}}\]\[4{{s}^{2}}\] \[{{M}^{3+}}\] \[1{{s}^{2}}\], \[2{{s}^{2}}2{{p}^{6}}\] ,\[3{{s}^{2}}3{{p}^{6}}3{{d}^{5}}\] \[4{{s}^{0}}\] Hence, 13 electrons are present in the \[M-\]shell of\[{{M}^{3+}}\]state.You need to login to perform this action.
