Rutherford Experiment

Question 1

Describe the Rutherford experiment?

Answer 1

alpha particle scattering experiment
alpha particles directed at gold foil
most alpha particles pass straight through
(so) most of atom is empty space
a few alpha particles deflected through large angles
(so) mass is concentrated at centre of atom
(and) nucleus is (positively) charged
plum pudding model has mass spread throughout atom
plum pudding model has charge spread throughout atom
