Question

which observation by ernest rutherford and his students refuted the plum pudding model? (1 point) electron attraction electron deflection alpha particle deflection alpha particle attraction

Explanation:

Rutherford's gold - foil experiment involved shooting alpha particles at a thin gold foil. The plum - pudding model predicted that the alpha particles would pass straight through or be slightly deflected. However, the observation of alpha particle deflections (some at large angles) refuted the plum - pudding model as it indicated the presence of a small, dense, positively - charged nucleus.

Answer:

alpha particle deflection
