In a hydrogen atom, an electron with n = 7 can exist in how many different quantum states?
A)6
B)7
C)15
D)33
E)98

Question

Quizplus · Accepted Answer

The number of quantum states for an electron in a hydrogen atom with principal quantum number n is given by n^2. For n = 7, the number of states is 7^2 = 49. However, considering all possible combinations of quantum numbers (n, l, m_l, m_s), the total number of states is 2n^2 = 98.
