The quantum mechanical model of the hydrogen atom requires that if the orbital quantum number of the hydrogen atom is 3,there will be how many permitted orbital magnetic quantum numbers?
A) three
B) nine
C) four
D) seven

Question

Quizplus · Accepted Answer

The magnetic quantum number (m_l) can take values from -l to +l, where l is the orbital quantum number. For l = 3, m_l can be -3, -2, -1, 0, 1, 2, 3, which gives a total of 7 possible values.
