take “first orbit” to mean “first orbital”, because orbitals are what electrons have instead of orbits. Another name for the first orbital is the “S orbital”, which can also be called an “S state”, since an orbital is a state function for a bound electron.
The first orbital is the orbital with lowest total of kinetic plus potential energy, because electrons tend to radiate, hence to settle into the available state of lowest energy. Since only one electron can occupy each state function, they occupy successively higher-energy states, so the lowest-energy state is the first state to be occupied as electrons are successively added.
Different angular momentum is one way states can differ from each other. Increasing angular momentum increases the kinetic energy. Also, increasing kinetic energy increases average distance from the nucleus, thus reducing the magnitude of the negative energy of electrostatic attraction between negatively charged electron and positively charged nucleus.
Consequently, the first orbital of a hydrogen atom, or of any other atom, has zero angular momentum. Consequently, one would have to wait forever for it to make even one revolution.
