Atoms “strive toward stability” by trying to fill the outer energy-level shell to the maximum stable number of 8. This is commonly illustrated by the bonding of sodium and chlorine atoms (Fig. 2.2). Explain how this happens.
Answer to relevant QuestionsRefer to Fig. 2.2. After sodium gives an electron to chlorine, are they still electrically neutral atoms?
