Split of d-Orbitals

In an atom, d-orbitals are a set of five regions where electrons are likely to be found. When these atoms are placed in a magnetic or electric field, or inside certain compounds, these d-orbitals split into groups with slightly different energies—a process called "splitting." This occurs because the environment's symmetry affects how the electrons in these orbitals interact with surrounding charges. The splitting influences how atoms bond and their color, magnetic properties, and reactivity. Essentially, the d-orbitals' energy levels change depending on their surroundings, shaping how the atom behaves chemically and physically.
