He though that atoms are tiny, uncuttable, solid particles that are surrounded by empty space and constantly moving.He conducted in combining elements.
-
He proposed that all substances are made of atoms.Atoms of the same element are exactly alike.Atoms of different elements are different.Elements combine in specific proportions.
-
Electrons are found in electron clouds, not paths.Electrons jump between levels from path to path.Electron paths cannot be predicted.
-
He conducted the gold foil experiment.There is a small, dense, positively charged nucleus.Electrons move in empty space in the atom.
-
Electrons travel in definite paths.
-
He conducted the cathode-ray experiment.His theory of the atomic structure lead to the "plum-pudding" model.
