Abstract:
Students had difficulty understanding the chemical bonding concept because of its complex and abstract
nature. This difficulty could lead to chemical bonding misconceptions. This study aimed to investigate basic
chemistry students' misconceptions of chemical bonding. This study used a descriptive research design with a
four-tier diagnostic test. The research’s subjects were basic chemistry students. Chemical Bonding Diagnostic
Tool (CBDT) was used as an instrument to determine students' misconceptions. The results showed that
students who had misconceptions about ionic, covalent, and coordinate covalent bonding were 48.9%, 53.0%,
and 37.5%, respectively. The misconception in this course is that students need to learn about ionic bonds
formed by electrostatic forces between cations and anions. As a result, students cannot determine the
difference in electronegativity values in ionic and covalent bonds and the number of valence electrons of each
atom in a chemical bonding. Therefore, the misconception is in the moderate category.
