In the Bohr model, a number of electrons will normally occupy a single orbit (or level), but the maximum number that can be at any level is strictly limited (two in the first, eight in the second, and eight in the third). For example, helium has two electrons orbiting at the first level; lithium has the third electron in a higher orbit.
The system of limiting the number of electrons in an orbit an excluding others is called the Pauli Exclusion Principle
