What is the Periodic Trend Calculator?

The Periodic Trend Calculator helps visualize and understand trends of chemical properties in the periodic table. By selecting a property (like electronegativity, atomic radius, ionization energy, or electron affinity) and the direction (across a period → or down a group ↓), it explains how that property changes. This tool is useful for students and chemistry enthusiasts to quickly review patterns in element behavior without memorizing each trend.

How to Use:

1. Select Property: Choose a property such as electronegativity, atomic radius, ionization energy, or electron affinity.
2. Select Direction: Pick whether you want to see the trend across a period (→) or down a group (↓).
3. Click “Calculate”: The calculator generates a clear explanation of how the selected property changes in the chosen direction.
4. Review the Result: Use the explanation to understand or memorize periodic trends and predict chemical behavior.
