An atom is in a state with orbital quantum number ℓ=2.Possible values of the magnetic quantum number m_ℓ are: A)1, 2 B)0, 1, 2 C)0, 1 D)-1, 0, 1 E)-2, -1, 0, 1, 2

Question

Quizplus · Accepted Answer

The possible values of magnetic quantum number, m, range from -ℓ to +ℓ, in integer steps. For ℓ=2, the possible values of m are -2, -1, 0, 1, 2, which corresponds to a total of 5 possible values. Therefore, the correct answer is E, which includes all possible values of m for ℓ=2.
