Question

Stable electron configurations are likely to contain  A. high-energy electrons.	  B. unfilled s orbitals.	  C. fewer electrons than unstable configurations.	  D. filled energy sublevels.

anonymous · Answer

D, a full energy level is most stable and 'prevents' the atom from giving or receiving electrons under normal conditions, i.e. inactivity of noble gasses (furthest column on the periodic table)
