A positively charged particle used to probe atomic structure in the gold-foil scattering experiment.
Revise: Development of the Atomic ModelIn the gold-foil scattering experiment carried out in 1909, Rutherford’s team directed a beam of positively charged alpha particles towards a very thin sheet of gold foil. They observed the directions in which the particles travelled after reaching the foil. Scattering means a change in a particle’s direction.
