- B( 2,1,-1,+ 1 2 )
- C( 3,1,1, 1 2 )
- D( 3,0,0, 1 2 )
Correct answer
C. ( 3,1,1, 1 2 )
Step-by-step solution
Electronic configuration for C l(Z=17) is 1 s² 2 s² 2 p⁶ 3 s² 3 p⁵ array |c|c|c|c| m₁ & -1 & 0 & -1 3 p⁵ & 1 l & 1 l & 1 array The values of quantum number for the above configuration is array |c|c|c|c| n & I & m₁ & m_ s 3 & 1 & 1 & 1 2 array
