About this app

Molecule Builder - Interactive Chemistry Learning App

Discover the fascinating world of chemistry through hands-on molecular construction! Molecule Builder is an educational application designed for students, teachers, and chemistry enthusiasts of all ages.

CORE FEATURES

Drag & Drop Interface
Build molecules intuitively by dragging atoms from the palette directly onto the workspace. Our smooth touch and mouse support ensures a seamless experience on any device - from smartphones to desktop computers.

Smart Chemical Bonding System
Atoms automatically form bonds when placed within 120 pixels of each other. The intelligent bonding algorithm respects chemical valence rules, creating realistic molecular structures. Watch as single, double, and triple bonds form dynamically based on atomic properties and proximity.

Extensive Atom Library
Access over 45 elements from the periodic table, organized into categories:
- Non-metals (H, C, N, O, P, S)
- Halogens (F, Cl, Br, I)
- Noble Gases (He, Ne, Ar, Kr, Xe)
- Alkali Metals (Li, Na, K, Rb, Cs)
- Alkaline Earth Metals (Be, Mg, Ca, Sr, Ba)
- Transition Metals (Fe, Cu, Zn, Ag, Au, and more)
- Metalloids (B, Si)

Each atom displays its chemical symbol, full name, and valence number for educational reference.

Molecule Recognition Database
Create compounds and instantly identify them! Our database contains over 100 known molecules including:
- Basic molecules: Water (H2O), Oxygen (O2), Nitrogen (N2)
- Hydrocarbons: Methane (CH4), Ethane (C2H6), Propane (C3H8), Benzene (C6H6)
- Alcohols: Methanol, Ethanol, Propanol, Glycerol
- Acids: Sulfuric acid, Nitric acid, Acetic acid, Citric acid
- Salts: Sodium chloride (NaCl), Calcium chloride, Magnesium sulfate
- Organic compounds: Glucose (C6H12O6), Sucrose, Amino acids
- Industrial chemicals: Ammonia (NH3), Carbon dioxide (CO2)

Each recognized molecule displays its common name, chemical formula with proper subscripts, and a direct link to PubChem for detailed scientific information.

Customizable Favorites
Select up to 10 favorite atoms for quick access. Your preferences are automatically saved and persist between sessions, allowing you to personalize your workspace for specific chemistry topics or experiments.

Visual Bond Rendering
A real-time canvas system draws chemical bonds between connected atoms. Bond strength is visually represented through opacity - closer atoms show stronger, more defined connections. Double and triple bonds are rendered with parallel lines for accurate representation.

Intuitive Workspace Management
- Drag atoms freely within the workspace to rearrange molecular structures
- Remove unwanted atoms by dragging them to the trash zone
- Clear the entire workspace with one tap to start fresh
- Responsive design adapts to any screen size

Educational Tools
Built-in reference section displays popular molecules with their formulas, helping beginners learn common chemical compounds. The app uses the Hill system for formula notation, matching standard scientific conventions.
