The theory is that all atoms are all created individually and cannot be seperated, no matter what scientific procedures are applied.
-
All matter is made of atoms. Atoms are indivisible and indestructible.
All atoms of a given element are identical.
Compounds are formed by a combination of two or more different kinds of atoms. -
He used the Cathode Ray Tube to prove his theory. Thomson found the particle called electron.
-
thought that an atom has a central nuclues. Electrons move in orbit like the rings around saturn.
-
He thought atoms had a central postive nucleus surrounding by negative orbiting electrons.
-
He thought electrons move in spherical orbits at fixed distances from the nuclues.
-
He used mathematical equations to describe the motion of electrons in atoms. His work leads to electron cloud model.
-
He comfirmed the existence of nuetrons, which have no charge. Atomic nuclei contain neutrons and positively charged protons.
