The atomic orbit mentioned in quantum mechanics refers to the trajectory of electrons described by mathematical functions. According to relevant public information, the atomic orbit in quantum mechanics refers to the trajectory of electrons in atoms and is a mathematical function describing the state of electrons. Because atoms are three-dimensional objects and electrons exhibit wave-particle duality, it is impossible to accurately determine the position and trajectory of electrons in quantum mechanics. On the contrary, we can only predict the possibility of electrons appearing in a region, which is the atomic orbit. Atomic orbit is a mathematical model to describe the spatial configuration of electrons in atoms. It describes the position and probability density of electrons and can be used to explain the chemical properties and spectral phenomena of elements. There are different types of atomic orbital shapes, such as S, P, D and F, and each type has a different quantum number, which can be used to describe the energy, angular momentum and magnetic quantum number of electrons in atoms.
