Question
If the magnetic quantum number (ml) has values of -1, 0, and +1, what is the corresponding value of the angular momentum quantum number (l)?
Correct Answer
Option B is the correct answer.
Detailed Explanation
The magnetic quantum number ml takes values from -l to +l. If ml has values -1, 0, and +1, this set contains 3 values, which corresponds to l = 1. For l = 1, ml can be -1, 0, and +1, representing the three p orbitals.
Hint
The number of ml values equals 2l + 1. Solve for l when there are 3 ml values.
