ChemLab: Periodic Table

ChemLab is a complete, offline chemistry toolkit for high-school and college students. Explore the full periodic table of 118 elements and solve real problems with eight built-in chemistry tools — no internet connection required.

PERIODIC TABLE
• All 118 elements with four levels of detail: basic properties, atomic data, electronic and physical properties, history and real-world uses.
• Search by name, symbol, or atomic number.
• Landscape wide view and a clear category colour legend.

CHEMISTRY TOOLS
• Molar Mass Calculator — get the molecular weight of any formula, with a per-element breakdown. Supports brackets and hydrates (e.g. CuSO4·5H2O).
• Equation Balancer — balance any chemical equation in one tap.
• Empirical Formula Calculator — find the empirical formula from mass percentages.
• Molecular Formula Calculator — get the molecular formula from the empirical formula and molar mass.
• Solubility Checker — look up whether an ionic compound is soluble.
• Reaction Predictor — predict the products of common reactions (synthesis, decomposition, single and double replacement, combustion, neutralization).
• Ion Engine — 43 ions with detailed data.
• Worksheet Generator — create practice problems and export them to PDF.

WHY CHEMLAB
• Works fully offline — study anywhere, anytime.
• Accurate: molar masses, balanced equations, and reaction products are checked so you learn the right chemistry.
• Clean, fast, distraction-free interface with a dark theme.
• Save favorite elements and ions, and keep a history of your calculations.

PERFECT FOR
• High school and college chemistry students
• GCSE, A-Level, IB, AP and general chemistry courses
• Anyone who needs a quick molar mass calculator, chemical equation balancer, or a molecular weight lookup on the go.
