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