6b) Explain Dalton Atomic theory and update and what the theory means for matter.

6c) State what Thomson found and his Plum Pudding Model.

6d) Explain how Rutherford gold leaf experiment shows the structure of the atom (and location of each subatomic particle type (i.e. proton, electron, neutron).

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, Gay-Lussac, 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).

*h) Explain Bohr's (planetary model of the atom) theory of the atom including distance electron from nucleus = energy in electron, how electrons move in atoms (ground state of atom, excited state of atom, electron in lower energy level, electron in higher energy level).

*Will leave charged cloud model (quantum mechanical model) of atom until next chapter/test.

6b) Explain Dalton Atomic theory (called Solid State Atomic Model) and update and what the theory means for matter.

6c) State what Thomson found and his Plum Pudding Atomic Model.

6d) Explain how Rutherford gold leaf experiment (his model is called Nuclear Model) shows the structure of the atom (and location of each subatomic particle type (i.e. proton, electron, neutron).

6e) Explain Bohr's Planetary Model of Atom including energy levels and # of electrons in each energy levels.

7) Be able to understand the difference between an ion and an atom with respect to number of electrons compared to number of protons. Also, be able to understand and draw symbolic representation of both cation and anion (the two different types of ions).
