<center>2020-2021 Objectives of Atomic Structure - Thru Rutherford</center> 
 
Essential Questions (EQ2): Are there any basic particles ? 
 
 
The student should be able to (bold numbers are MA Framework Standard numbers):

1. Trace the development of atomic theory and the structure of the atom from the Greeks to the present (Dalton, Thompson, Rutherford, Bohr, and charge cloud model).

*a) Memorize what the significant contribution to the atomic structure from Boyle, Stahl, Priestley, Lavoisier, Proust, <nowiki>Gay-Lussac</nowiki>, Avogadro 
*b) Understand the four part of Dalton Atomic Theory, how we have updated his original theory, and the importance of his theory. 
*c) Be able to calculate Law of Definite Proportion problems.
*d) Explain, using the experiment set-up and the results, how Thomson came up with the concept of electron (and the fact that their is only one type of electron). From his work, explain the atomic model, Plum pudding model of the atom. 
*e) Memorize what the following scientist did: Millikian (oil drop expt, determine actual mass & charge of electron), Goldstein (discovered proton), and Chadwick (discovered neutron).
*f) Memorize the actual mass, charge and location of all three subatomic particles (i.e. electrons, protons, and neutrons). 
*g) Explain, using the Gold leaf experiment set-up and the results, how Rutherford came up with the concept of nucleus (remember, there are 3 characteristics) and how the electrons move outside the nucleus. Explain Rutherford shortcomings.
