They are called electron rings, so called because the electrons whizz around the nucleus following these rings. It's basically the orbit of the electron around the nucleus, like the moon orbits around the Earth. They're not strictly rings though, they're more a random pattern. Does that make sense?
They are normally referred to as orbits or shells. In each shell, electrons inhabit sub-levels where the most important ones are called orbitals. Each of the orbits or shells may only hold a fixed number of electrons.
Atoms do not have rings. Often they're drawn like they do, but in reality, the electrons travel around the nucleus in a random manner within electron zones. Usually the zones are called "electron clouds". They have different shapes depending how many electrons the atom has and the zones are organized from closest to the nucleus to farthest. http://www.universetoday.com/38282/electron-cloud-model/
