The quantum mechanical model of the hydrogen atom requires that if the orbital quantum number = 7,there will be how many permitted orbital magnetic quantum numbers allowed?
A)6
B)7
C)11
D)15

Question

Quizplus · Accepted Answer

The magnetic quantum number (m_l) can take values from -l to +l, including zero. If the orbital quantum number (l) is 7, then m_l can be -7, -6, -5, ..., 0, ..., +5, +6, +7, which gives a total of 15 possible values.
