👉 In quantum physics, an orbital is a specific configuration of electrons in atoms and molecules. It is named after the way electrons can occupy different energy levels within the nucleus when they are allowed to move through space. Orbital configurations are determined by the principle of Pauli exclusion principle, which states that no two electrons of the same angular momentum quantum number (n) can occupy the same energy level (l). This means that each electron in an orbital must have a specific energy level. The orbitals
