1.	Give the value of the azimuthal and magnetic quantum number of the electrons in an atom when n=4
Answer» The magnetic quantum number specifies the orientation in space of an orbital of given energy and shape. This number divides the subshell into individual orbitals which hold the electrons; there are (2L+1) orbitals in each subshell. Thus, the s subshell has only one orbital, the p subshell has three orbitals, and so on. For n=4, we have s,p,d,f subshells. For s subshell, we have 2×0+1=1. For p subshell, we have 2×1+1=3. For d subshell, we have 2×2+1=5. For f subshell, we have 2×3+1=7. The total value of m will be 1+3+5+7=16 The principal quantum number is given as n=4 Thus the azimuthal quantum number has values, l=0 to (n−1). ∴l=0,1,2 and 3

Answer»

The magnetic quantum number specifies the orientation in space of an orbital of given energy and shape. This number divides the subshell into individual orbitals which hold the electrons; there are (2L+1) orbitals in each subshell. Thus, the s subshell has only one orbital, the p subshell has three orbitals, and so on.

For n=4, we have s,p,d,f subshells.

For s subshell, we have 2×0+1=1.
For p subshell, we have 2×1+1=3.
For d subshell, we have 2×2+1=5.
For f subshell, we have 2×3+1=7.

The total value of m will be 1+3+5+7=16

The principal quantum number is given as n=4

Thus the azimuthal quantum number has values, l=0 to (n−1).

∴l=0,1,2 and 3
