Atoms constantly move
Atoms are small, hard particles -

-
All substances are made of atoms. Atoms of different elements are different. Atoms of the same elements are exactly the same. Elements combine in specific proportions. He conducted experiments in combining elements.

He conducted the cathode-ray tube experiment. His theory of the atomic structure lead to the "plum-pudding" model. There are small, negatively charged particles inside an atom.

-
Atoms contain mostly empty space. He conducted the gold foil experiment. Most of an atom's mass is in the nucleus. There is a small, dense, positively charged nucleus. Electrons move in empty space in the atom.

-
Electrons jump between levels from path to path. Electrons travel in definite paths.
-
-
Electron paths cannot be predicted. Electrons are found in electron clouds, not paths.
