-
he found that atoms are small, hard particles that are constantly moving and he thought that were "uncuttable".
-
This is what Democritus atom for their time
-
He found out that atoms of different elements are different and atoms of the same elements are exactly alike. He also did experiments in combining elements and found elements combine in specific proportions.
-
He thinks it looks the same as Democritus
-
He conducted the cathode-ray tude experiment. His theory of the atomic structure lead to the "plum-pudding" model. He found that there are small, negatively charged particles inside an atom.
-
Found that their are positive and negative charges
-
He conducted the gold foil experiment and found most of an atom's mass is in the nucleus. also the electrons move in empty in the atom and atoms contain mostly empty space.
-
found that the positive elections are in one spot
-
Bohr found that electrons jump between levels from path to path. And he found that electrons travel in definite paths.
-
He thought that there were rings going around it.
-
they found that there is a cloud around the atom not rings
-
They found that electron paths cannot be predicted .And that electron are found in electron clouds, not paths
