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

Question

Quizplus · Accepted Answer

For an electron in a hydrogen atom, the number of different quantum states for a given principal quantum number n 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 and spin-down), doubling the number of quantum states to 98.
