What is the atomic orbit in college chemistry? Is it an eight-character orbit attached to the energy level?

The number 8 is the p orbit.

Atomic orbit is the "orbit" of electrons outside the nucleus, that is, wave function, which is divided into high energy and low energy. It is solved by Schrodinger equation. According to the angle distribution, there are S, P, D, F, G, H ... (energy from low to high).

It's all in college inorganic books.
