Periodic Trends Map
The whole periodic table is painted as a heatmap. Switch the property to recolor all 118 elements, then hover or drag across the table to read exact values — the side plot draws that property across the highlighted period or down the highlighted group so the trend jumps out.

Why it matters
Why explore this?
Chemistry connects events too small to see with changes we can measure. This model helps you link particles, energy, and conditions to an observable result.

Questions to test
Predict first, try it in the model, then use what you observe to answer.
What to try
- Map atomic radius. Why do the atoms get bigger as you move down a group but smaller as you move left to right?
- Switch to ionization energy. Why does it climb toward the top-right corner — the exact opposite of radius?
- Trace electronegativity down group 17 (the halogens). Where does the strongest electron-grabber sit, and why fluorine?
- Look at electron affinity across period 2. Why do nitrogen and the noble gases refuse to fit the smooth trend?
- Compare the transition metals in a period against the main-group elements. Why are their trends so much flatter?
Explain
Make sense of what happened
Describe what happened at the particle or energy level, then connect it to the result you saw. A strong explanation names both the cause and the evidence.
