Question

The correct set of quantum number for the unpaired electrons of chlorine atom is:

• A. $3,1,1,\pm \frac{1}{2}$
• B. $2,1,-1,+\frac{1}{2}$
• C. $3,0,0,\pm \frac{1}{2}$
• D. $2,0,0,+\frac{1}{2}$

Answer 1

The correct option is A $3,1,1,\pm \frac{1}{2}$

The correct set of quantum number for the unpaired electrons of $chlorine$ atom is $n=3,l=1,m=1,s=\pm \frac{1}{2}$.

The electronic configuration of $chlorine$ atom is $\left[Ne\right]3s^{2}3p^5$.

The unpaired electron is present in $3p$ orbital.
