Homework Due Monday Mar 14

Put your NAME and the DATE DUE on all assignments. 


1) Fill out the "What I've Done" and "What I will do" (for this past week and next week respectively) and email me by SUNDAY NIGHT.  DO NOT FORGET *grrrrrrrr*


2) Post a comment on the blog when you begin working on the assignment "I've begun the assignment"


3) Answer the questions below pertaining to the "Atomic Theory" documents
1) What is a standing wave?
2) What is the new model of the atom which replaced the Bohr model?
3) Explain this sentence: “Instead of the simple circular planetary orbits of the Bohr model, solving the Schrodinger equation results in a description of three-dimensional shapes of the patterns that develop when electron waves are confined by a nucleus.”
4) A man weighs 60 kg.  How fast must he travel in order for his wavelength to match that of red light?
5) Describe the experiment which shows that electrons have wave properties.
6) Contrast the orbits of the Bohr model to the orbits of Shrodinger’s model.  Describe the motion of electrons and the shape of the orbits.
7) What does the following mean: “A wave is not localized like a particle.”
8) What is meant by a “fuzzy electron cloud”?
9) Explain: “The quantum mechanical theory is not an extension or refinement of the Bohr model.”
10) In the quantum-mechanical model, the electron is considered to be a spread-out wave.  Where exactly then are the electrons located?
11) The higher the energy of the electron, the _____ (nearer or farther) the electron is to the nucleus.
12) List the names of the four quantum numbers.
13) Write the electron configuration for fluorine.
14) List the three orbitals which come after 2p.
15) What is a “cell” of the periodic table?
16) Explain this sentence “The arrangement has a meaning, both about atomic structure and about chemical behaviors.”
17) What does “facilitate your understanding” mean?
18)  Nitrogen has more similarities to _______ (oxygen or phosphorus)?
19) Give an example of a very soft, shiny metal which is highly reactive with water.
20) List all elements described in the text book as “reactive” (includes both metals and non-metals).
21) What does “inert” mean?
22) How many electrons are in the outer-most orbital of tin?
23) The electrons of which orbitals are responsible for chemical reactions?


4) Read Light Document 1 and take a minimum of 2 pages of notes.  Follow the *special* note guidelines below.
Remember the process for how to read text books that we discussed in class?  Try it out today when you read the light document!  Start by reading the chapter outline, scanning all headings throughout the reading and glancing at the diagrams.  Write your thoughts and questions as you get an oveview of the chapter. I want to see TONS of questions written down!  As always, make note of new vocabulary words. Write something like this:


First-over scan of the chapter:
Outline - sources of light
In class we've only talked about light coming from accelerating charged particles and also about light being emitted by all objects due to their temperature - I'm wondering what types of light sources will be discussed in the book
Key words in bold -
incandescent - we read about this
black-body radiation - I've heard of this
Headlines - "Light Interacts with Matter" - I don't know much about this at all

5) Read Light Document 2 and take a minimum of 2 pages of notes.  Follow the *special* note guidelines.
