Answer:
0, 1, 2, 3
General Formulas and Concepts:
<u>Chemistry - Atomic Structure</u>
- Principal Energy Level <em>n</em> (1 to ∞)
- Angular Momentum ℓ (n - 1)
- Magnetic mℓ
- Electron Spin ms
Explanation:
<u>Step 1: Define quantum number</u>
Principal Energy Level <em>n</em> = 4
<u>Step 2: Define ℓ</u>
ℓ is the Angular Momentum. Its values start at 0, 1, 2, 3...
It is the Principal Energy Level <em>n</em> minus 1 (n - 1).
<u>Step 3: Find</u>
n = 4
ℓ = 4 - 1 = 3
Therefore, out angular momentum values can be 0, 1, 2, 3. These correlate to s, p, d, f sublevels.
