Homework Answers
11 a)
- All electrons that have the same value for n (the principle quantum number) are in the same shell
- Within a shell (same n), all electrons that share the same l (the angular momentum quantum number, or orbital shape) are in the same sub-shell
- When electrons share the same n, l, and ml, we say they are in the same orbital (they have the same energy level, shape, and orientation)

Which of the following set of quantum numbers (ordered
n,l,ml,ms) are possible for an electron in an atom?
Quantum Number Rules Learning Goal: To learn the restrictions on each quantum number. Quantum numbers can be thought of as labels for an electron. Every electron in an atom has a unique set of four quantum numbers. The principal quantum number n corresponds to the shell in which the electron is located. Thus n can therefore be any integer. For example, an...
