Electron Configurations: Where Transition Metals Choose Chaos

Electron Configurations: Where Transition Metals Choose Chaos

Electron configurations should follow a nice, predictable pattern based on the periodic table. Then Chromium and Copper show up with their "exceptional" configurations, breaking all the rules you just memorized. Instead of following the expected [Ar]4s²3d⁴ pattern, Chromium goes rogue with [Ar]4s¹3d⁵ because apparently having a half-filled d-orbital is more "stable." Copper pulls the same stunt with [Ar]4s¹3d¹⁰ for its completely filled d-orbital. Chemistry really enjoys watching students suffer through these "exceptions" that professors always test on. Nothing like spending hours memorizing rules just to learn there are random vegetables that don't follow them.
