#l=2#

Explanation:

The angular momentum quantum number, #l#, is used to denote the subshell in which a given electron resides in an atom.

The value of the angular momentum quantum number depends on the value of the principal quantum number, #n#, as given by

#l = {0, 1, 2, ..., n-1}#

Now, in order for an electron to be located in a #d# orbital, it must be located in the #d# subshell. The angular momentum quantum number designates

  • #l = 0 -># the s subshell
  • #l=1 -># the p subshell
  • #l=2 -># the d subshell
  • #l=3 -># the f subshell

In your case, all the electrons located in a #d# orbital will share the same value of the angular momentum quantum number, i.e. #l=2#.
