Different shells can hold different maximum numbers of electrons. Electrons occupy shells starting with the innermost one. They begin to occupy the next shell when a shell becomes full.

For elements in the first three periods of the periodic table (hydrogen ... have the following electon configurations. Writing out all the orbitals can be a bit laborious and so a frequent shorthand ...

The ions formed have a full outer electron shell, so are very stable. See the study guide on groups in the periodic table for more information.
