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

Answer: (A)

The positive charge is concentrated in a very small volume of the atom.

Answer 2

: As a very few $\alpha$ - paricles were deflected by sharp angles it was concluded that the positive charge is concentrated in a very small volume of the atom.
