Final answer:

In a subshell where the angular momentum quantum number (ℓ) is 2, there are five orbitals allowed.

Step-by-step explanation:

When the angular momentum quantum number ℓ is equal to 2, the subshell has a total of five orbitals. This is derived from the magnetic quantum number mℓ, which can have values of 0, ±1, or ±2 for ℓ = 2. Consequently, each of these five orbitals can hold up to two electrons each, with opposite spins, resulting in a maximum of ten electrons that the subshell can accommodate according to the formula 2(2ℓ + 1).
