The incorrect set of quantum numbers (n, l, m, s) for an electron in 3 p orbital is
Options
- A3,1,-1,1 / 2
- B3,1,-2,-1 / 2
- C3,1,1,1 / 2
- D3,1,+1,-1 / 2
Correct answer
B. 3,1,-2,-1 / 2
Step-by-step solution
For an electron in 3p-orbital, the values of aligned n & =3 l & =0, 1, 2( value of l are form 0 to n-1) m & =0 -1,0,+1,-2,-1,0,+1,+2 aligned ( For each value of l , the value of n varies from -l to 0 to +l ) Also, for every value of m , the values of s can be +1 / 2 and -1 / 2 . Option (b) is incorrect, as for n=3 , the value of m cannot be -2 .
