### Step-by-Step Solution: 1. **Understanding Alpha Particles**: Alpha particles are positively charged particles consisting of two protons and two neutrons. They are emitted during certain types of radioactive decay. 2. **Experiment Setup**: In the Rutherford experiment, a thin foil (usually gold foil) is used to observe the behavior of alpha particles when they are directed towards it. 3. **Observation of Alpha Particle Behavior**: When alpha particles are fired at the thin foil, most of them pass straight through without any deflection. This indicates that the majority of the atom is empty space. ...
