Lewis structures, also known as electron-dot structures, are diagrams that represent how the electrons are arranged around each atom in a molecule or ion. Drawing Lewis structures is an important skill that students need to acquire in the introductory chemistry curriculum. It is the starting point for understanding and predicting some physical and chemical properties, such as molecular geometry using the Valence Shell Electron Pair Repulsion Theory (VSEPR), acidity and basicity, reactivity, polarity, intermolecular forces, and solubility etc. However, a number of studies stated that students had difficulties drawing Lewis structures. mentioned the confusion about writing the correct number of multiple bonds when students drew a Lewis structure. Additionally, Cooper et. al noted that drawing Lewis structures was more difficult for students in the following circumstances: (a) increased molecular complexity, such as change from one-to two-carbon species, and (b) the formula was presented without structural cues even for some simple molecules.
