The 3d subshell, a neighborhood for eight electrons, is almost fully occupied. Instead of snuggling up together, these electrons defy the odds and spread out into four individual orbitals, each containing a single electron. This arrangement maximizes their privacy and minimizes their discomfort.

Unveiling the 3d Electron Distribution

The 3d subshell is divided into five orbitals, labeled dxy, dyz, dzx, dx²-y², and dz². According to Hund's rule, electrons will first occupy individual orbitals before pairing up.
