Passage II
In an atom, an electron exists in one of several quantum states (configurations). Each quantum state can be specified by a set of numbers. Two of these numbers are called n and j. In addition, each quantum state is associated with a type of orbital (a region surrounding the nucleus).
The figure shows, for n ≤ 4 in a hydrogen atom, every possible combination of n and j for which a quantum state exists. The figure also shows, for each state, the energy—which is determined by the values of n and j—and the orbital type: s, p, d, or f.
7. Based on the figure, which of the following combinations of n, j, and orbital type does NOT correspond to a quantum state ?
n j orbital type
Your Answer is
Correct Answer is D
Explanation
When n=4, j=5/2, there are only d and f, so choose D
