A) \[5,\,0,\,0,+\frac{1}{2}~\]
B) \[5,\,\,1,\,\,0,\,\,+\frac{1}{2}\]
C) \[5,\,\,1,\,\,1,\,\,+\frac{1}{2}\]
D) \[6,\,\,0,\,\,0,\,\,+\frac{1}{2}\]
Correct Answer: A
Solution :
The electronic configuration of \[_{37}Rb\] is: \[1{{s}^{2}},\,2{{s}^{2}}2{{p}^{6}},\,3{{s}^{2}}3{{p}^{6}}3{{d}^{10}},\,4{{s}^{2}}4{{p}^{6}},\,5{{s}^{1}}\,\]\[\operatorname{n}=5,\,\,l=0,\,\,m=0,\,\,s=+\frac{1}{2}\,\,or\,\,-\frac{1}{2}\]
