Bond Type Predictor
Pick an atom for each side and watch the shared electrons drift toward whichever atom pulls harder. The bigger the electronegativity difference (ΔEN), the more lopsided the sharing — until the electrons are handed over completely and the bond turns ionic.

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
- Put the same atom on both sides (F and F). Where do the electrons sit, and why is that bond nonpolar?
- Pair sodium with chlorine. At what point do the electrons stop being shared and get transferred outright?
- Build the O–H bond found in water. Which atom ends up slightly negative?
- Can you find two atoms whose ΔEN lands right on a boundary between bond types? What happens to the animation there?
- Keep one atom fixed and swap the other through the whole row. How does the electron pull track the electronegativity difference?
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.

If you can answer all three using evidence from the model, you understand the main idea. If not, return to Explore and change one setting at a time.
