Very few bombarded α-particles on gold foil were deflected by sharp angles and therefore, it was concluded that the positive charge is concentrated in a very small volume of the atom called nucleus.
Most of the particles passed through the foil undeflected and was concluded that most of the space in an atom is empty.
A very few α-particles (approx. 1 in 12,000) were bounced back.
So option A is only incorrect statement.

Explanation:
Rutherford's α-particle scattering experiment was conducted to understand the structure of the atom. In this experiment, a beam of α-particles was directed at a thin gold foil and their behavior was observed. Based on the observations, we can determine the correct and incorrect statements.
1. Some of the α-particles rebound after hitting the gold foil (Incorrect)
- Rutherford's experiment showed that some of the α-particles were deflected or bounced back after hitting the gold foil.
- This observation led to the conclusion that the atom contains a small, dense, positively charged nucleus, which repelled the α-particles, causing them to rebound.
- Therefore, statement A is incorrect because some α-particles did rebound.
2. Some of the particles deflected from their path (Correct)
- Rutherford observed that some of the α-particles were deflected at different angles as they passed through the gold foil.
- This observation suggested that the atom is mostly empty space with a small, dense nucleus, which caused the deflection of the α-particles.
- Therefore, statement B is correct.
3. Some of the particles not pass through the gold foil (Correct)
- Rutherford observed that some of the α-particles did not pass through the gold foil and were either deflected or rebounded.
- This observation indicated that the gold foil was not completely transparent to α-particles.
- Therefore, statement C is correct.
4. Most of the particles pass straight through the gold foil (Incorrect)
- Rutherford found that most of the α-particles passed straight through the gold foil without any deflection.
- This observation was unexpected as the prevailing model at that time, Thomson's plum pudding model, suggested that the positive charge was uniformly distributed throughout the atom.
- Therefore, statement D is incorrect because most of the α-particles did not pass straight through the gold foil.
In conclusion, statement A is incorrect because some of the α-particles did rebound after hitting the gold foil.
