-
atoms contain mostly empty space
-
there is a small, dense, positively charged nucleus

Electrons travel in different paths
-
electrons jump between levels from path to path
-
he conducted thecathode-ray tube experiment
-
there are small, negatively charged particles in an atom
-
his theory of atomic structure became the "plum pudding" model
-
There are small, negatively charged particles in an atom
-
electons are found in electron clouds, not paths
-
electron paths cannot be predicted
-
atoms of different elements are different
-
most of an atom's mass is in the nucleus
