-
Atoms are "uncuttable"
Atoms are small, hard particles
Atoms constantly move -
Atoms are homogeneous meaning they have no internal structure. He stated atoms was solid, and stated all atoms differ in size, shape, mass, position and arrangement, with a void exists between them.
-
All substances are made of atoms
Atoms of different elements are different
Atoms of the same element are exactly alike
Elements combine in specific proportions
He conducted experiments in combining elements -
All matter is composed of very small things
-
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. -
The atom was a sphere embedded with electrons. The sphere had positive positive charges throughout it and negatively charged particles were also scattered across this model.
-
Atoms contain mostly empty space
Electrons move in empty space in the atom
He conducted the gold foil experiment
Most of an atom's mass is in the nucleus -
The electrons were embedded in a positively charged atom like plums in a pudding.
-
Electrons jump between levels from path to path
Electrons travel in definite paths -
The electrons could only orbit the nucleus in certain special orbits at different energy levels around the nucleus.
-
Electrons are found in electron clouds, not paths. - Both
Electron paths cannot be predicted. - Schrodinger -
The nucleus is in the middle
