Emphasizing the Significance of Electrostatic Interactions in Chemical Bonding
Venkataraman, Bhawani
Journal of Chemical Education, v94 n3 p296-303 Mar 2017
This paper describes a pedagogical approach to help students understand chemical bonding by emphasizing the importance of electrostatic interactions between atoms. The approach draws on prior studies that have indicated many misconceptions among students in understanding the nature of the chemical bond and energetics associated with bond formation and dissociation. The paper also presents an activity designed to help students conceptualize and demonstrate their understanding of relevant principles. To assess the effectiveness of this approach, a series of pre- and posttest questions and specific questions on the final exam was used to evaluate students' understanding of concepts. Analyses of this assessment reveal that emphasizing the significance of electrostatic interactions and the role of potential energy in chemical bonding helps students articulate why atoms form chemical bonds. Consequently, students recognize the energetics associated with bond formation and dissociation and are able to apply this understanding to specific chemical reactions.
