Chemistry Dude

Chemistry Dude is an interactive general chemistry toolkit built by a classroom chemistry teacher for students and teachers in first-year courses.
Explore the periodic table, visualize trends in 3D, draw Lewis structures, and practice with intelligent flash cards that focus on what you need most.

Core features
—Periodic Table: Clean, attractive table with essential data for every element, ideal for quick lookups during class, homework, or exams. Tap any element to jump directly into deeper details.
—Element Details: View physical and chemical properties, oxidation states, ionization energies, and full electron configurations for each element in one convenient screen. Great for problem sets, labs, and test prep.
—Lewis Structure Builder: Draw simple and complex Lewis structures for elements and molecules with guided tools. Use it to check your work, demonstrate bonding concepts, or project examples during lessons.
—Periodicity Visualized: See periodic trends as interactive graphs, including atomic mass, density, atomic radius, electronegativity, electron affinity, ionization energies, melting points, and boiling points. Many plots are shown as manipulable 3D graphs, making periodic patterns easier to see and explain.
—Electron Distribution in 3D: Explore orbitals and suborbitals with a 3D, manipulable representation through the seventh energy level. Compare any two elements side by side or build your own hypothetical configuration by filling suborbitals.
—Smart Flash Cards: Create custom decks from the elements and properties you want to study, then learn them in your chosen order, by atomic number, or at random. An adaptation of the Leitner spaced-repetition system places cards in virtual boxes and shows your weak spots more often so you remember them better.

Made for classrooms and self-study
—For students: Use Chemistry Dude as a portable reference, visualization tool, and study coach throughout your general chemistry course.
—For teachers: Project graphs and 3D models, build fast examples in class, and assign targeted flash card decks for quizzes and exam review.
