Quizplus · Accepted Answer

According to the quantum mechanical model of the hydrogen atom, the number of different permitted orbital quantum numbers is equal to the principal quantum number (n). Therefore, if the principal quantum number is 6, there will be 6 different permitted orbital quantum numbers (l = 0, 1, 2, 3, 4, 5). The answer is C.
