He conducted experiments in combining elements, atoms are small, hard particles, atoms constantly move.
-
All substances are made of atoms, Atoms are uncuttable, Atoms of different elements are different, Atoms of the same element are exactly alike, Elements combine in specific proportions.
-
Electron paths cannot be predicted, Electrons are found in electron clouds, not paths.
