A) \[n=2,\,l=1,\,\,m=0\]
B) \[n=2,\,l=0,\,\,m=-1\]
C) \[n=3,\,l=0,\,\,m=0\]
D) \[n=3,\,l=1,\,\,m=-1\]
Correct Answer: B
Solution :
Key Idea: For \[n=0\] to \[\infty ,\,\,l=0\] to \[n-1,\,m=-1\]to 0 to \[+\,l,\,s=\frac{1}{2}\]or \[-\frac{1}{2}\] use this information to find the correct choice [a] \[n=2,\,l=1,\,\,m=0\] it is possible [b] \[n=2,\,l=0,\,\,m=-1\] it is not possible because if \[l=0\], m must be 0. The value of m totally depends upon the value of \[l\] (\[m=-l\] to \[+\,l\]). [c] \[n=3,\,\,l=0,\,\,m=0\] it is possible [d] \[n=3,\,\,l=1,\,\,m=-1\] it is possible.
