Question

Identify the orbitals described by the following quantum numbers and arrange them in order of increasing energy.
(I) n=3 l=2 m=0
(ii) n=4 l= 0 m =0
(iii) n=4 n=2 m=-1
(iv) n=3 l=1 m=-1
(v) n=3 l=0 m=0​

Answer 1

Answer:

n= 3,l= 2=| 3d

Explanation:

Answer

1. The quantum numbers n=4,l=2,m

1

=−2,m

s

=−1/2 represents 4d orbital.

2. The quantum numbersn=3,l=2,m

1

=1,m

s

=+1/2 represents 3d orbital.

3. The quantum numbersn=4,l=1,m

1

=0,m

s

=+1/2 represents 4p orbital.

4. The quantum numbersn=3,l=2,m

1

=−2,m

s

=−1/2 represents 3d orbital.

5. The quantum numbersn=3,l=1,m

1

=−1,m

s

=+1/2 represents 3p orbital.

6. The quantum numbersn=4,l=1,m

1

=0,m

s

=+1/2 represents 4p orbital.

The order of increasing energies is (v)<(ii)=(iv)<(vi)=(iii)<(i).
