Question

Write the values of all azimuthal and magnetic quantum number if $n=2$?

• A. $l=0,1;m=\pm 1,0$
• B. $l=0,1;m=0$
• C. $l=1;m=\pm 1,0$
• D. $l=0,1;m=\pm 1$

Answer 1

The correct option is A $l=0,1;m=\pm 1,0$

When $n=2$, the azimuthal quantum number $l=0,1$
When $l=0$ , the magnetic quantum number $m=0$ and when $l=1$, the magnetic quantum number $=+1,0,-1$
