Question

Rutherford scattering showed nucleus is?

RankGuru · Accepted Answer

1. **Experiment**: Alpha particles were fired at a thin gold foil.
2. **Observations**: Most passed through, but a few were deflected at very large angles (some even backwards).
3. **Inference**: To deflect a positive alpha particle backwards, there must be a concentrated **positive charge** and substantial **mass** in a very tiny volume.
4. **Conclusion**: This led to the discovery of the **nucleus**, which contains nearly all of the atom's mass and its entire positive charge, while being thousands of times smaller than the atom itself.
