During class on 8/26/13, we refreshed our memories on basic chemistry. We were given a choice to pick which worksheet we wanted to work on, and I choose the one about making molecular models. Our objective was to practice reading formulas, counting atoms, visualizing atomic bonding, representing bonding using dot diagrams, and predicting and clarifying bonds as either ionic or covalent. On the worksheet we were given formulas and we had to count the atoms, draw the model and dot structure, and say if it was polar or non polar. This activity was informative and fun. This exercise was to prepare us for an oral quiz on basic chemistry that we had next.
