CHEMIVIUM is a free, web-based educational platform designed to make chemistry more visual, interactive, and accessible to students and teachers.
The platform combines interactive simulations, visual explanations, learning resources, and practical tools to help learners explore chemistry across different levels of representation — from atoms and subatomic particles to chemical bonds, molecules, and reactions.
With CHEMIVIUM, students can build and explore atoms and isotopes, investigate electron configurations and valence electrons, observe the formation of ionic and covalent bonds, explore three-dimensional molecular structures, and follow chemical reactions at macroscopic, microscopic, and symbolic levels. The platform also includes activities on equation balancing, ionic equations, spectator ions, conservation of mass, and other core chemistry concepts.
CHEMIVIUM is supported by a bilingual Knowledge Hub in Italian and English, which provides structured explanations, worked examples, diagrams, common misconceptions, self-check questions, and classroom-oriented activities. A collection of free chemistry tools is also available for calculations and concept reinforcement.
The resource is suitable for lower and upper secondary education and can be used for whole-class teaching, independent study, revision, homework, CLIL activities, and formative assessment.
CHEMIVIUM was created by mathematics and science teacher Daniele Preani with the goal of helping students not only read about chemistry, but see relationships, explore models, make predictions, and connect symbolic representations with observable phenomena.
No installation is required: CHEMIVIUM runs directly in a modern web browser and is available free of charge for educational use.
