Question

Which experiments provide more accurate measurements of nuclear size and help determine the distribution of charge inside the nucleus?

Options

• Measurement of the distance of closest approach

• Expansion of atoms to stadium size for observation

• Alpha-particle scattering experiments

• Electron scattering experiments

Answer 1

More accurate measurements of nuclear size come from electron scattering experiments. These experiments help determine the distribution of charge inside the nucleus and give a better estimate of the nuclear radius than alpha-particle scattering.
