Essential Question: Do you believe that? (theory explains observations)
Enduring Understanding: What colorful lights, Exciting is it not.
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 ancient Greeks to the present (Dalton, Thompson, Rutherford, Bohr, and charge cloud model). [2.1](2.1)
a. Memorize the following people and their major accomplishments (as I discussed in class):Greeks (Democratis& Leucippose), Alchemist, Robert Boyle, George Stahl, Joseph Priestley, Antione Lavoisier, Henry Cavendish, Joseph Proust, and Robert Millikan.
b. Understand the four part of Dalton Atomic Theory, how we have updated his original theory, and the importance of his theory.
c. 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.
d. 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.
e. 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).
f. Will leave charged cloud model of atom until next chapter/test.
2. Explain what light is in terms of DeBroglie, Planck (particle characteristics), and light characteristics.
3. Describe the electromagnetic spectrum in terms of wavelength and energy; identify regions of the electromagnetic spectrum. [2.6]
4. Be able to calculate, energy, wavelength and frequency using all appropriate equations and how the variable relate to each other (e.g. direct vs, indirect proportion).
5. Be able to explain the significant of a bright line spectra and what each line indicates (mean with respect to the atom).
