-
He thought that all substances were built up from four elements He used a model that desribed matter
-
Thought that all matter consisted of extremely small particles that could not be divided, called them atoms.
-
He thought tht all matter is made up of indiviual particles called atoms, which cannot be divided.
-
Maxwell-Boltzmann distribution for molecure speeds in a gas, where the particles do not constantly interact with each other but move freely between short collisions.
-
He thought that all particles are made up of smaller particles
-
He thought that an atom has a central nucleus and electrons move around it, made saturian mode. Got most of his work from Ludwig Boltzmanns. The model was based on an anology of the explanations for the stabillity of thr rings of Satern.
-
He thought that the mass and positive charge are evenly spread throughout an atom, did the gold foil experiment
-
He propses that moving particles like electrons have some properties of waves. Within a few years evidence is collected to support this idea. This helped scienetist understand that the atom didnt behave like the solar system because electrons do not move in regular orbits.
-
Deelops mathmatical equations to desribe the motion of electrons in atoms. his work leads to the electron cloud model
-
Confirms the existence of neutrons, which have no charge. Atomic nuclei contain neutrons and positively charged protons
