Question

Column -I	Column-II
A. $2s$	(P) $n=4,l=2,m=0$
B. $2p_z$	(Q)$n=4,l=2,m=-2or+2$
C. $4d_{x^2-y^2}$	(R) $n=2,l=1,m=0$
D. $4d_z^2$	(S) $n=2,l=0,m=0$

Match the column -I with column -II

• A. $A-S,B-R,C-Q,D-P$
• B. $A-Q,B-P,C-S,D-R$
• C. $A-R,B-S,C-P,D-Q$
• D. $A-S,B-R,C-P,D-Q$

Answer 1

The correct option is A $A-S,B-R,C-Q,D-P$

We know that,
$n$ = Principal quantum number which represents the energy level of the orbital.
$l$= Azimuthal quantum number which have the value $n-1$
m= magnetic quantum number which have the value $-lto+l$
For, $2s\Rightarrow n=2,l=0,m=02p_z\Rightarrow n=2,l=1,m=04d_{x^2-y^2}\Rightarrow n=4,l=2,m=-2or+24d_z^2\Rightarrow n=4,l=2,m=0$
