The correct Answer is:
### Step-by-Step Solution: 1. **Understanding Rutherford's Experiment**: - Rutherford conducted an experiment using alpha particles directed at a thin gold foil. 2. **Observation of Alpha Particle Behavior**: - Most alpha particles passed through the gold foil without any deflection. This indicated that the majority of the atom is empty space. 3. **Deflection of Some Alpha Particles**: - A small number of alpha particles were deflected at small angles, and a few were deflected back at angles close to 180 degrees. 4. **Conclusion on Atomic Structure**: - The deflections suggested that there was a concentrated mass within the atom that repelled the positively charged alpha particles. 5. **Identification of the Nucleus**: - Rutherford concluded that this concentrated mass must be a small, dense, positively charged center within the atom, which he named the nucleus. 6. **Final Statement**: - Therefore, Rutherford's model suggests the existence of the nucleus in an atom.
