In a hydrogen atom, an electron with n = 7 can exist in how many different quantum states?
A) 6
B) 98
C) 7
D) 15

Question

Quizplus · Accepted Answer

The number of different quantum states for an electron in a hydrogen atom with principal quantum number n = 7 is given by n^2. Therefore, for n = 7, the number of different quantum states is 7^2 = 49. However, each state can have two different spin orientations (spin up or spin down), doubling the number of quantum states to 98.
