For n = 4 and l = 2, give the sublevel designation, the allowable ml values, and the number of orbitals.

Sublevel designation is 4d.

The allowable values are -2, -1, 0, +1, +2

Number of orbitals in 4d sublevel are 5.

Explanation: Principle Quantum number or 'n' tells us about the number of orbits.

Azimuthal Quantum number or 'l' tells us about the sub-levels. It is calculated by the formula

Magnetic quantum number of tells us about the number of orbitals. Its value ranges from

When n = 4, value of l = 0, 1, 2, 3 which designated s, p, d and f sub-level respectively.

Sub-level designation for the given values is 4d.

Number of orbitals = 5
