A hydrogen atom is in the 6h state. Which one of the following is not a magnetic quantum number?
A) 0
B) 1
C) 2
D) 4
E) 6

Question

Quizplus · Accepted Answer

The maximum value of magnetic quantum number (m) is always equal to the principal quantum number (n) minus one, which in this case is five (6-1=5). Therefore, the choices of magnetic quantum numbers that are valid for a 6h state hydrogen atom are 0, ±1, ±2, ±3, ±4, and ±5. Choice E (6) is not a valid magnetic quantum number for this state.
