Electron Configuration Calculator — Frequently Asked Questions
Q1 What are the exceptions to the Aufbau principle? ▾
Elements like Chromium ([Ar] 3d⁵ 4s¹) and Copper ([Ar] 3d¹⁰ 4s¹) promote a 4s electron to achieve half-filled or fully filled 3d subshells, which provide extra thermodynamic stability.
