Expert Answer

Step 1

Principal quantum number:

 n = 1 to ∞ (infinity).

n = 1,2,3,4,5…………..∞.

Azimuthal or angular momentum quantum number:

l = (n-1) values.

l = 0,1,2,3,      up to (n-1)

magnetic quantum number:

ml = -l to +l

spin quantum number:

ms = -1/2 or +1/2.

Step 2- A. n = 2, l = 1

Principal quantum number:

 n = 1 to ∞ (infinity).

n = 1,2,3,4,5…………..∞.

Azimuthal or angular momentum quantum number:

l = (n-1) values.

l =upto  (2 -1) values= 0, 1

Therefore, given set of quantum numbers(n = 2, l = 1) are possible.

 

Possible quantum numbers are:

Shell

n

Subshell

l

Orientation

ml

Spin

ms

2

1

1, 0, +1

 -1/2 or +1/2.

 

Step 3: B. n = 3, l = 0.

Principal quantum number:

 n = 1 to ∞ (infinity).

n = 1,2,3,4,5…………..∞.

Azimuthal or angular momentum quantum number:

l = (n-1) values.

l =  upto (3 -1) values

l = 0, 1, 2.

Therefore, given set of quantum numbers(n = 3, l = 0.) are possible.

 

Possible quantum numbers are:

Shell

n

Subshell

l

Orientation

ml

Spin

ms

3

0

0

 -1/2 or +1/2.
