The research aims to develop an AR app as a learning tool to facilitate first-year university students in comprehending the concept of the chemical properties and investigate students' performance in understanding the concept of the chemical properties of main group elements. The app was developed using Unity, Vuforia, Canva, and Blender. A mixed method was employed in the R&D adopting ADDIE development model. Twenty-two students of chemistry education department at a state university in Aceh, Indonesia participated in the need analysis and implementation stage. The data was collected through questionnaires, and a system usability scale. The students' performance was evaluated through online Quizizz platform. The findings reveal a strong consensus among students regarding the necessity of AR for comprehending chemistry concepts. The students responded positively to the app's attractiveness, ease of use, impact on their learning experience, alignment with teaching materials, and markers quality, yielding a mean score of 91.8%. The application is ease to use with a SUS score of 84.9. The N-Gain score indicates positive impact to the students' performance. AR app of periodic properties of elements demonstrates feasibility and serves as a viable alternative teaching tool for the concept of periodic properties of elements. © 2024 the author(s), published by De Gruyter, Berlin/Boston.
