The electron states in an atom which constitute a single shell all have:
A) the same value of n 
B) the same value of 
C) the same value of n and the same value of 
D) the same value of and the same value of 
E) the same set of all four quantum numbers

Quizplus · Accepted Answer

The value of n represents the principal quantum number, which determines the energy level of the electron. Therefore, all electron states in a single shell have the same value of n. The other quantum numbers (l, ml, and ms) may differ between the electron states within the same shell.
