D) 4 0 0 -1/2
Correct Answer: D
Solution :
The electronic configuration of potassium is \[_{19}K=1{{s}^{2}},\text{ }2{{s}^{2}},\text{ }2{{p}^{6}},\text{ }3{{s}^{2}},\text{ }3{{p}^{6}},\text{ }4{{s}^{1}}\] For \[4{{s}^{1}},\] \[n=4\] \[l=0\] (\[\because \]For s orbital,\[l=0\]) \[m=0\] \[s=-\frac{1}{2}\]You need to login to perform this action.
