Quantum Model of Chemical Bonding: Barriers and Learning Difficulties

Abstract

Understanding mysteries of the material cohesion must pass through the mastery of the concept “chemical bonding”. However, the literature shows that the concept is perceived as abstract and difficult for students of all grade levels and academic .Among university students, in addition to the confusion caused by the plurality of chemical bonding models, the quantum approach is a source of major difficulties impeding the deep understanding of the concept. The research presented here consists of investigations with undergraduate students built around the fundamental concepts of the quantum model of the chemical bonding. The results show that the fundamental concepts of the quantum chemical bonding model are partially mastered.
