This research describes the mental model of covalent bonding for high school and vocational high school students involving 240 respondents from 5 provinces in Indonesia, namely Sumatera Utara, Lampung, Bali, Kalimantan Timur, and Nusa Tenggara Timur. The results of this study are very useful for knowing the mental models of students, especially in the era of the COVID-19 pandemic. Students' mental model on understanding covalent bonds in this study, obtained by distributing questions to students, aims to determine the level of understanding of each student by involving three levels of chemical phenomena, namely macroscopically by explaining a brief description of the questions in each question, then sub macroscopic by asking students to describe the Lewis structure, as well as the symbolic level by solving the equation for the formation of compounds. Data were obtained from the covalent bond mental model results and the results of interviews with student representatives. Based on Park's mental model classification (2009) found that 32% of students had a second intermediate mental model, while 29% of pupils had the first intermediary mental model, and 39% of pupils had an initial mental model or an unformed mental model.
