The value of `l`is generally designated by the eletters `s,p,d…`. Thus, if `l = 4`, we have a//an_______orbital.

Options

A. `f`
B. `g`
C. `d`
D. `p`

Answer

B

Explanation

Thus, if `l = 0`, we have an `s` orbital, if `l = 1`, we have a `p` orbital, and so on.
The unusal sequence of letters `(s,p`, and `d)` has a historical origin. Scientists who studied atomic emission spectra tried to correlate the observed spectral lines with the particular enegry states involed in the transitions. they noted that some of the lines were sharp, some were rather spread out or diffuse, and some were very strong and, hence, referred to as principle lines. subsequently, the initial latters of each adjective were assigned to those enegry states. However, after the letter `d` and starting with the letter `f`, the orbital designations follow alphabetical order.
