Using preprinted diagrams depicting Lewis dot formulas for group 17 atoms, group 16 atoms and group 15 atoms, describe and demonstrate how these atoms can achieve a stable octet of electrons in their valence energy levels. Compare the results to a preprinted diagram showing the sharing of electrons and the formation of a single covalent bond. Repeat the process using double bonded binary atoms and triple bonded binary atoms. Once complete and discussed, use molecular models and have Ben construct the single, double, and triple bonded molecules and compare their bond lengths.
