Ø

·       Read the subsection titled “The Formation of a Covalent Bond” on page 338 of your text. The text discusses bond formation in terms of potential energy changes. It’s not too obvious. As an exercise to make this clearer, answer the following questions based on Coulomb’s Law: (a) why is energy input required to move the nuclei from point 3 to point 2? The negatively charged electrons exert an attractive force on the two positively charged nuclei. (b) Why is energy input required to move the nuclei from point 3 to point 4? The positively charged nuclei repel each other. (c) Consider point 1.5 on the curve, halfway between point 1 and 2 on the horizontal axis. Why is very little energy input required to move the nuclei from point 1.5 to point 1? The bonding electrons are distant from the positively charged nuclei so the attractive force between electrons and protons is diminished in this region of the graph.
