Copper's Electron Configuration Rebellion

Chemistry students experiencing copper's electron configuration for the first time be like... 😱 The transition metals are the drama queens of the periodic table! While most elements fill their electron shells in a nice, predictable order, copper says "nah, I'm special" and yeets an electron from the 4s to the 3d orbital for extra stability. It's literally the atomic equivalent of stepping in something gross and then discovering you're wearing your favorite shoes. The energy payoff from having a full d-subshell is so worth the quantum mechanical rebellion! Next time your professor asks why Cu is [Ar]3d¹⁰4s¹ instead of [Ar]3d⁹4s², just show them this and walk away like a boss.
