Elementary chemistry and physics teach us that positively and negatively 
valent elements can combine to form compounds. Completion of electronic shell 
structures are explained as a rational for such compound formations. Then one 
hears about compounds of negatively valent elements such as chlorine dioxide 
that flies in the face of that rational. Can you explain?
