Which term refers to the notation used for representing the arrangement of electrons in orbitals?

The term that accurately describes the notation used for representing the arrangement of electrons in orbitals is "orbital notation." This notation visually represents the electrons in an atom's orbitals, using arrows to indicate the spin of the electrons and boxes to represent the orbitals themselves. In orbital notation, different orbitals (such as s, p, d, and f) are depicted along with their corresponding electron configurations, clearly showing how electrons occupy these orbitals based on principles such as the Pauli exclusion principle and Hund's rule.

The other terms, while related to the broader topic of electron configuration, do not specifically describe the notation format. For example, "quantum representation" is a more generic term that might refer to the quantum mechanical aspects of electron behavior but does not capture the specifics of how electrons are depicted in orbitals. Similarly, "energy level notation" generally relates to the principal quantum number and indicates the energy levels of electrons but does not illustrate their arrangement within those levels. "Sublevel notation" refers to how electrons are organized within specific energy sublevels (such as 2s, 2p), but again, it does not encompass the visual representation of electrons in their orbitals as effectively as orbital notation does.
