Question

Based on his alpha ray scattering experiment, Rutherford made which of the following deductions about the atom?
Options
A Electrons are placed in discrete 'stationary orbits'.
B The atom is a uniformly positive sphere.
C Most part of the atom is an empty space.
Correct Answer
D Atoms of the same element have the same mass.
Correct Answer

Option C is the correct answer.

Detailed Explanation

Rutherford's alpha ray scattering experiment led to several deductions, including that 'Most part of the atom is an empty space'. He also deduced that 'The nucleus is at the centre of an atom, where most of the charge and mass is concentrated' and that 'Electrons revolve around the nucleus in a circular orbit, like the way planets orbit the sun.'

Hint

Consider what the scattering experiment revealed about the distribution of matter and charge within the atom.
