Question

The correct set of four quantum number values for the valence electron of sodium atom is

• A. n=3,l =1,m=1,s=-$\frac{1}{2}$
• B. n=3,l =0,m=0,s=+$\frac{1}{2}$
• C. n=3,l =0,m=1,s=+$\frac{1}{2}$
• D. n=3,l =1,m=0,s=-$\frac{1}{2}$

Answer 1

Answer: (B)

n=3,l =0,m=0,s=+$\frac{1}{2}$

Answer 2

The correct option is (B): n=3, l =0, m=0, s=$+\frac{1}{2}$
