Solution: Can an electron in an atom be in an energy level described by the set of quantum numbers n = 5, ℓ = 3, m ℓ = -2?1. No, because m ℓ cannot be negative.2. No, because ml must be equal to ±1.3. Yes4. No, because n cannot be as large as 5.5. No, because ℓ must be equal to n -1.

Problem

Can an electron in an atom be in an energy level described by the set of quantum numbers n = 5, ℓ = 3, m ℓ = -2?

1. No, because m  cannot be negative.

2. No, because ml must be equal to ±1.

3. Yes

4. No, because n cannot be as large as 5.

5. No, because ℓ must be equal to n -1.
