118 Elements

Search all 118 elements by name, symbol, number, or category.

🌀

Atom Model

Use a clearly labelled first-20 Bohr-shell learning model.

🧪

Tools

Calculate formula mass, balance equations, and apply solubility rules.

📝

Practice

Worksheets and quizzes.

Interactive Periodic Table

Search by name, symbol, atomic number, or category. Atomic weights follow the abridged IUPAC table used for education.

100%Use the controls or Ctrl + mouse wheel. Tap any element for details.

Electron Shell Explorer

Explore all 118 elements. IGCSE learners should focus mainly on the first 20 shell arrangements; later elements are included as an advanced reference because their electron structures involve additional subshells. The circular display is a learning model, not a literal electron path.

Atomic number—

Electron arrangement—

Valence electrons—

Likely ion—

Electrons are moving at normal speed.

Purpose of the controls: Play and Pause control the learning animation; Speed changes the pace; 3D view separates the shell levels visually. The motion is a learning visualization—not a literal path followed by electrons.

Common Ions

Learn names, formulae, charges, types, molar masses, and common uses.

Chemistry Learning Workspace

Each tool teaches the method, shows every step, and then checks the final result.

Molar mass: formula → atom count → calculation

1 · DecodeIdentify each element and subscript.

2 · MultiplyAtoms × atomic mass.

3 · AddSum all contributions in g/mol.

Enter a valid formula such as H2O, CO2, Ca(OH)2, or Al2(SO4)3.

Equation balancing board

Conservation of mass: the number of atoms of every element must be equal on both sides. Change coefficients only—never subscripts.

Select an equation, count atoms, then reveal the process.

Solubility rule coach

Apply the strongest rule first: Group 1, ammonium, and nitrate salts are soluble. Then check halide, sulfate, hydroxide, and carbonate exceptions.

Choose both ions to predict the compound’s solubility.
