Complete the statement

The {0} principle says no two electrons in an atom may share the same set of four quantum numbers. {1} rule says pairing does not begin until every orbital of the subshell is {2} occupied.

Both rules together produce the electronic structure of the atom. Source: syllabus Chemistry Part I, Ch 2 Structure of Atom.
