Chemistry You Can See and Touch – Right in Your Browser
Zperiod is not just a digital version of the traditional periodic table – it’s a complete interactive educational environment, combining 3D atomic models, advanced chemistry tools, a simple virtual lab, and a smart worksheet generator.
🔗 Official Website: zperiod.app – Available in multiple languages (English, Arabic, Spanish, French, and more)
What Does Zperiod Offer?
⚛️ Complete Interactive Periodic Table
- 118 chemical elements with detailed data (atomic number, atomic mass, electron configuration, valences, electronegativity, and more)
- 3D atom models for every element – rotate and zoom to see electrons and nucleus
- Ions tab – view common ions for each element with their charges
- Flexible filtering – filter elements by group, period, state (solid/liquid/gas), or classification (metals, nonmetals, transition metals…)
🧪 Integrated Chemistry Tools (Grades 9-12)
| Tool | Function |
|---|---|
| Equation Balancer | Automatically balance complex chemical equations with visual stoichiometry feedback |
| Molar Mass | Instantly calculate molecular weights with a detailed element-by-element mass breakdown |
| Solubility Table | Interactive charts and rules for ionic compound solubilities – quick reference while solving problems |
| Virtual Lab | Simple lab scene where you can tilt a beaker and interact with water particles – basic reaction simulation |
📝 Smart Worksheet Generator
- Generates practice questions from real, commonly taught reactions
- Perfect for teachers preparing quick class exercises or students self-practicing
- One click: “Generate Worksheet” – get new problems in seconds
🌍 Flexible Global Units
You can change the global units (temperature, density, energy) according to your country’s system (SI, Imperial, etc.)

How Teachers Use Zperiod in the Classroom
Scenario 1: Explaining Atomic Structure
- Open the periodic table, choose an element (e.g., carbon)
- Rotate and zoom the 3D atom model with touch or mouse
- Discuss with students: Where are the electrons? What does the nucleus look like?
Scenario 2: Balancing Chemical Equations
- Enter an unbalanced equation like
H2 + O2 -> H2O - Click “Equation Balancer” – students see the balancing steps with visual explanation
- Compare their manual method with the automated result
Scenario 3: Quick Practice – Molar Mass and Solubility
- Assign students a random compound (e.g.,
Na2SO4) - Ask them to calculate the molar mass manually, then verify using the Molar Mass tool
- For ionic compounds, check the solubility table to see if it precipitates in water
Scenario 4: Instant Worksheet
- Click “Worksheet Generator” → select difficulty level or topic → click “Generate”
- Print or distribute the worksheet digitally to students within one minute
Quick Comparison with Other Free Alternatives
| Platform | Zperiod | Ptable | ChemDoodle Web |
|---|---|---|---|
| 3D atom model | ✅ (all elements) | ❌ | ✅ (limited number) |
| Equation balancer | ✅ (built-in) | ❌ | Partial (paid for full features) |
| Molar mass with breakdown | ✅ | ❌ | ❌ |
| Worksheet generator | ✅ | ❌ | ❌ |
| Multiple language support | ✅ (including RTL) | Partial (basic menu translation) | Limited |
| Virtual lab | ✅ (basic) | ❌ | ✅ (advanced but paid) |
| License | Fully free | Free | Freemium |
Verdict: Zperiod excels in practical chemistry tools (balancing, molar mass, question generator) compared to its competitors, with the unique addition of 3D atomic models for all 118 elements.
