For l = 2, how many orbitals are possible?

Answer:

For l = 2, the value of m possible are -2.-1,0,+1,+2.

Magnetic quantum number(ml)

The value of the magnetic quantum number is dependent on the value of the azimuthal or orbital angular momentum quantum number. For a given value of l, the value of ml ranges between the interval -l to +l. Therefore, it indirectly depends on the value of n.

Azimuthal Quantum Number (l) Value Corresponding Number of Orbitals (2l + 1) Possible Values of ml
0 (‘s’ subshell) 2 × 0 + 1 = 1 0
1 (‘p’ subshell) × 1 + 1 = 3 -1, 0, and 1
2 (‘d’ subshell) × 2 + 1 = 5 -2, -1, 0, 1, and 2
3 (‘f’ subshell) × 3 + 1 = 7 -3, -2, -1, 0, 1, 2, and 3
