Question

Which of the following conclusions regarding the structure of atom is based on Rutherford's $\alpha$-particle scattering experiment?

• A. The positive charge is concentrated in a very small volume of the atom
• B. The positive charge is scattered with the electrons throughout the atom
• C. The volume occupied by the nucleus is half of the volume of atom
• D. Most of the space in the atom is occupied by the neutrons

Answer 1

The correct option is A The positive charge is concentrated in a very small volume of the atom

As a very few $\alpha$-particles were deflected by sharp angles it was concluded that the positive charge is concentrated in a very small volume of the atom.
Hence, option $\left(a\right)$ is the correct answer.
