Question

Match List-$I$ with List-$II$ and select the correct answer using the codes given below in the lists ($n,l$ and $m$ are respectively the principal, azimuthal and magnetic quantum no.)

List-I	List-II
(A) Number of value of $l$ for an energy level(n)	(1)0, 1 ,2 ,............ (n - 1)
(B) Values of $l$ for a particular type of orbit	$(2)+lto-l$ through zero
(C) Number of value of $m$ for $l$ = 2	(3)5
(D) Values of 'm' for a particular type of orbital	(4 )n

• A. (A)-(4),(B)-(1),(C)-(2),(D)-(3)
• B. (A)-(4),(B)-(1),(C)-(3),(D)-(2)
• C. (A)-(1),(B)-(4),(C)-(2),(D)-(3)
• D. (A)-(1),(B)-(4),(C)-(3),(D)-(2)

Answer 1

Answer: (B)

Number of values of $l=$ total number of subshells = $n$.
Value of $l=0,1,\mathrm{2.............}(n-1)$.
$l=2\Rightarrow m=-2,-1,0,+1,+2(5values)$
$m=-1to+1$ through zero.
