Upon completion of ch 4 students will be able to:

Describe ancient Greek models of matter.

 List the main points of Dalton’s atomic theory and describe his evidence for the existence of atoms.

 Explain how Thomson and Rutherford used data from experiments to produce their atomic models.

Identify three subatomic particles and compare their properties.

 Distinguish the atomic number of an element from the mass number of an isotope, and use these numbers to describe the structure of atoms.
