John+Dalton

John Dalton [|http://www.rsc.org/chemsoc/timeline//pages/1803.html] [] Summarize his theory of the atom. There are multiple parts to his model of the atom. Explain each and include visuals to help us understand each part.

Dalton's theory was based on the premise that the atoms of different elements could be distinguished by differences of their weights.
 * All matter is composed of atoms
 * Atoms cannot be made or destroyed
 * All atoms of the same element are identical
 * Different elements have different types of atoms
 * Chemical reactions occur when atoms are rearranged
 * Compounds are formed from atoms of the constituent elements



Erwin Schrodinger founded the equation to a wave. His equation had the same relation to the mechanics of the atom like Newton's equations of motion.

Schrodinger's wave equation

The major components of an atom are protons, neutrons, and electrons. These components are found in the nucleus.

Test Questions: 1) What is the Bohr Model used for? 2) What is the central region that the neutrons and protons occupy in the Bohr Model called? 3) Why are the planetary model and the Bohr Model of an atom similar to each other? 4) When can the atoms make transitions between the orbits?
