How to Use the Electron Configuration Practice & Orbital Capacity Tool
- 1 Enter the principal quantum number (n = 1, 2, 3, 4, etc.).
- 2 Read the total maximum number of electrons that can occupy that shell.
Electron Configuration Practice & Orbital Capacity Tool — Frequently Asked Questions
Q1 Why is the maximum capacity of the 3rd shell 18 electrons? ▾
The n = 3 shell contains one 3s orbital (2 electrons), three 3p orbitals (6 electrons), and five 3d orbitals (10 electrons), totaling 2 + 6 + 10 = 18 electrons.
