From the \( \alpha \) -particle scattering experiment, Rutherford concluded that: This question has multiple correct options
- A. \( \alpha \) -particles can approach within a distance of the order of \( 10^{-14} \mathrm{m} \) of the nucleus
- B. the radius of the nucleus is less than \( 10^{-14} m \)
- C. scattering follows Coulomb's law
- D. the positively charged parts of the atom move with extremely high velocities
Step-by-step solution
From the α-particle scattering experiment, Rutherford concluded that most of the mass and positive charge of an atom is concentrated in a very small region called the nucleus. The fact that some α-particles were scattered backwards implied that the nucleus has a radius less than about 10^{-14} m, which is orders of magnitude smaller than the atomic radius.
