Answer: a. n = 3, l = 2: The subshell in which electrons with these quantum numbers are found is the d subshell.
b. n = 1, l = 0: The subshell in which electrons with these quantum numbers are found is the s subshell.
c. n = 4, l = 3: The subshell in which electrons with these quantum numbers are found is the f subshell.
d. l = 3: It is not possible to determine the subshell in which electrons with this quantum number are found, as the principal quantum number "n" is not specified. The angular momentum quantum number "l" only specifies the shape of the orbital, not the energy level or subshell.
