Question

The correct set the quantum unpaired electron of chlorine atom is:

• A. n = 2, l = 1, m${}_1$ = 0
• B. n = 2, l = 1, m${}_1$ = 1
• C. n = 3, l = 1, m${}_1$ = 1
• D. n = 3, l = 0, m${}_1$ = 0

Answer 1

The correct option is C n = 3, l = 1, m${}_1$ = 1

Chlorine's electronic configuration,

$\left[Ne\right]3s^{2}3p_x^2{p}_y^2{p}_z^1$

3,0,0 3,1,-1 3.1.0 3.1.1

So correct set is :

$n=3,l=1,m=1$

Hence, the correct option is $\text{C}$
