Question

In Rutherford's alpha particle scattering experiment, when fast moving alpha particles were made to fall on a thin gold foil then most of the alpha particles passed straight through the foil. Which of the given conclusion is correct?

• A. Positive charge of the atom is concentrated in the centre of the atom.
• B. Positive charge and mass of the atom is distributed throughout the atom.
• C. Most of the space is occupied.
• D. Most of the space inside the atom is empty.

Answer 1

The correct option is D

Most of the space inside the atom is empty.

As most of the space inside the atom is empty therefore an alpha particle passed straight through the foil undeflected.
