A) \[3,1,0,\frac{1}{2}\]
B) \[3,1,1,\frac{1}{2}\]
C) \[3,2,1,\frac{1}{2}\]
D) \[3,0,0,\frac{1}{2}\]
Correct Answer: D
Solution :
: E.C. of Na \[\text{(}Z=11)=\text{ 1}{{s}^{2}}\text{ }2{{s}^{2}}\text{ }2{{p}^{6}}\text{ }3{{s}^{1}}\] Outermost electron occupies 3s orbital. \[\therefore \] \[n=3,\,l=0,\,m=0,\,s=\frac{1}{2}\]
