A) \[\text{1} {{\text{s}}^{\text{2}}}\text{,}\,\text{2}{{\text{s}}^{\text{2}}},\,\text{2}{{\text{p}}^{\text{5}}}\]
B) \[\text{1} {{\text{s}}^{\text{2}}}\text{,}\,{{\text{2}}_{\text{s}}}^{\text{2}}\text{,}\,\text{2}{{\text{p}}^{\text{6}}}\text{,}\,\text{3s}\]
C) \[\text{1} {{\text{s}}^{\text{2}}}\text{,}\,1{{\text{p}}^{\text{6}}}\text{,}\,2\text{s}\]
D) \[1{{s}^{2}},\,2{{s}^{2}},\,2{{p}^{6}},\,3{{s}^{2}}\]
Correct Answer: C
Solution :
\[1{{s}^{2}},1{{p}^{6}},2s\] is not a possible configuration, because here \[2+6=8\]electrons are shown in first orbit. While there can not be more than 2 electrons in first orbit.You need to login to perform this action.
