The electron moves with time and does not stay in one specific position, or on 1 specific circular orbit. Instead, it’s path is more of a cloud around and sometimes even inside the nucleus. Technically, the electron could go everywhere in space, but there is a cloud, called the orbital of the electron, where it is most likely to be found. So the time-average electron position is the orbital of the electron. For a hydrogen atom, the only electron is the 1s electron, which has a spherical orbital.
