ATOMIC THEORY CHAPTER 11.1 IN HOLT TEXTBOOK

BCE Ancient Greek Philosopher Matter divided into a smaller and smaller piece the uncuttable piece “atomos”

The Dalton Model The solid sphere model Atoms are seen as solid, indestructible spheres (like billiard balls) Explained how atoms join to make molecules and compounds Proposed 1 st atomic theory in 1803

JJ Thomson discovered electrons in 1897.

q-2HjM JJ Thomson’s Cathode Ray Experiment

The Rutherford Model British Physicist who discovered the nucleus in 1908 Atom is mostly empty space Discovered the small, positive nucleus

The Bohr Model Danish scientist Proposed the Planetary Model in 1913 Electrons move in definite orbits or energy levels

An atom consists of a dense nucleus composed of protons and neutrons surrounded by electrons that exist in different clouds at the various energy levels. Electron Cloud Model (1920’s)
