ERNEST RUTHERFORD
GOLD FOIL EXPERIMENT
1909 - Fired positivly charged particles at an extremely thin sheet of gold.
They expected postive particles to be delected because of previous work - the 'plum pudding'
Most of the particles passed straight throough the gold, with a small number deflected.
This famous experiment disproved the 'plum pudding' model'
This led to Rutherford's new idea - the nuclear atom: in effect he changed chemistry.
It described how nucleus is at centre surrounded by negative electrons.
