2.28 (i) An atomic orbital has n = 3. What are the possible values of l and ml?
For a given value of the principal quantum number , the azimuthal quantum number can have values from to .
Therefore, for given atomic orbital ,
The value of can take values from to , i.e., .
And for a given value of , the Magnetic quantum number can have values.
When value of then, ,
