Abstract
Chemical bonding was one of the concepts that were considered difficult by students because of its abstract nature. Students^ conceptual understanding could be different from each other. So that analysis was needed to determine students^ conceptual understanding. The purpose of this study was to investigate basic chemistry students^ conceptual understanding of chemical bonding. This study used a descriptive research design with 20 basic chemistry students of Universitas Billfath. Students^ conceptual understanding was determined by a four-tier diagnostic test, CBDT (Chemical Bonding Diagnostic Tool). The result showed that only 20,94% of students fully understand, 19,06% of students partially understand, 10,94% of students didn^t understand, and 49,06% of students had misconceptions about chemical bonding.
