| Consider die following sets of quantum numbers: [AIPMT (S) 2007] |
| \[n\] \[l\] \[m\] \[s\] |
| (i) 3 0 0 \[+1/2\] |
| (ii) 2 2 1 \[+1/2\] |
| (iii) 4 3 2 \[-1/2\] |
| (iv) 1 0 1 \[-1/2\] |
| (v) 3 2 3 \[+1/2\] |
| Which of the following sets of quantum number is not possible? |
A) ii, iii and iv
B) i, ii, iii and iv
C) ii, iv and v
D) i and iii
Correct Answer: D
Solution :
| The value of l varies from 0 to \[n-l\] and the value of m varies from \[-\,l\] to \[+l\] through zero. |
| The value of \['s'\,\pm \,\frac{1}{2}\] which signifies the spin of electron. The correct sets of quantum number are following: |
| n l m s |
| (ii) 2 1 1 \[+1/2\] |
| (iv) 1 0 0 \[-1/2\] |
| (v) 3 2 2 \[+1/2\] |
