Question

What values of ℓ are possible for a shell with n = 4

Answer 1

Answer:

0, 1, 2, 3

General Formulas and Concepts:

Chemistry - Atomic Structure

• Principal Energy Level n (1 to ∞)
• Angular Momentum ℓ (n - 1)

• Magnetic mℓ
• Electron Spin ms

Explanation:

Step 1: Define quantum number

Principal Energy Level n = 4

Step 2: Define ℓ

ℓ is the Angular Momentum. Its values start at 0, 1, 2, 3...

It is the Principal Energy Level n minus 1 (n - 1).

Step 3: Find

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.
