**Step-by-Step Solution:** 1. **Understanding the Experiment**: Rutherford conducted an experiment where he directed a beam of alpha particles at a thin gold foil. The purpose was to investigate the structure of the atom. 2. **Observing Deflections**: During the experiment, it was observed that most of the alpha particles passed straight through the foil, but a small fraction were deflected at large angles. This was surprising because, according to the plum pudding model of the atom at that time, the positive charge was thought to be spread out evenly throughout the atom. 3. **Analyzing the Deflections**: The large deflections indicated that there must be a concentrated area of positive charge within the atom that repelled the positively charged alpha particles. The closer the alpha particles came to this concentrated positive charge, the larger the deflection. ...
