Question

Explain Rutherford's gold foil experiment or alpha [α] particle scattering experiment ??

Answer 1

Answer:

was carried out to study atomic structure

alpha particles were directed at a thin gold metal foil in a vacuum, and the following results were obtained:

most alpha particles passed straight through the foil with no deflection; this indicated that most of an atom is empty space, and the nucleus is very small

few alpha deflected slightly ( less than 90 degrees); so, very few alpha pass close to the nucleus, which contains all the positive charge of an atom

even fewer deflected more than 90 degrees; most of the atom's mass is concentrated in the tiny, dense nucleus, which is at the atom's centre

hope this helps:)
