High school education often simplifies complex concepts in chemistry, leading to the misconception that shells, subshells, and orbitals are identical. Teachers typically avoid advanced mathematical explanations to accommodate students' foundational knowledge. The distinction between these terms becomes clearer with a deeper understanding of quantum mechanics and atomic structure. Resources like the Schrödinger equation provide a more accurate representation of atomic behavior, especially in multi-electron atoms. This simplification is intended to ease the learning process but can result in misunderstandings later on.
