Discovery of – Atomic nucleus:
- Discovery – Study of the atomic model leading to the discovery of – atomic nucleus.
Experiment:
- Rutherford projected alpha particles towards a thin gold foil, – in the path of the rays.
- He saw that most of the alpha particles went straight through the foil, – but some were deflected slightly & some by large angles.
Conclusion:
- An atom, on the whole, is relatively empty but consists of a – concentrated positive mass in the centre, which leads to the deflection of the alpha particles.
- Thus the discovery of a central positive region – atomic nucleus was initiated.
