Explanation:

Atoms with unstable outer energy levels combine with atoms that also have partially complete outer energy levels to achieve a more stable electron configuration. Atoms with full outer energy levels (like noble gas atoms) are already stable and do not readily combine. Atoms with no electrons in their outer energy levels would not be able to engage in electron - sharing, losing, or gaining in a way that stabilizes the initially unstable atom.

Answer:

atoms with partially complete outer energy levels
