STUDY STRATEGY FOR CHAPTER 17

I. Go through your review questions  and highlight the ones  you are not sure about
II.  download 'The Atomic PC' periodic table software ( or similar)  and load it  on your own computer so you can work off-line as well.
III. Go to the Los Alamos National Lab periodic table site http://pearl1.lanl.gov/periodic/default.htm and  download their table (there is a word, Adobe PF, and HTML version) so that you can work off-line
Explore these a little to see what information they contain. Look for any help or tutorials they have. (the Los Alamos download has sections about how to use the periodic table etc.)
IV. Look back through your review questions and see if any are clearer now. See if the table helps you figure any of them out.
Most  of the questions can be answered based on the table if you understand its structure and organization. It's basically a 'cheat-sheet'
 for scientist so they don't have to memorize all of that stuff.
V. GO back the Chapter 17 page on phyzx.net and scroll down through the page. Try out links to topics you are unclear on.
You will see section numbers corresponding to those in you book. On the web page there are links to resources that should help you with each part of this chapter.
Take some notes about the sites you visit  and whether or not they were help helpful to your understanding of  any of the concepts.  Print out a page or do a screen cap if it was any good. BOOKMARK  or  ADD to your FAVORITES any sites you visit
VII. FOCUS ON YOUR REVIEW QUESTIONS as a study guide.
It's great to explore all of this stuff but you are only being tested on your ability to answer those questions. 
VII. TURN IN YOUR ASSIGNMENTS ON TIME
IX. ACE THE EXAM

go here for...REVIEW QUESTION HELP  four million atoms could line up across the head of a pin.If the NUCLEUS had a diameter equal to that of a PINHEAD, then the ATOM itself would have a diameter of about 10 METERS.

Pinheads, Marbles, & Free Drinks

If a CHILD'S MARBLE TOY were made of ATOMIC NUCLEI it would WEIGH OVER 2.5 BILLION TONS!

If an atom were magnified until it was as large as a football stadium, the nucleus would be about the size of a grape.

A neutron walked into a bar and asked "how much for a drink?"  The bartender replied,  "for you... no charge!"

NOTICE: a large portion of this page are cut and pastes fHewitt's Chapter 17 Web Page
17.1 ELEMENTS

Chemicool Periodic Table- Produced by MIT student David Hsu, this periodic table is indeed cool! Choose an element by typing its name or clicking on the periodic table. A new page will load with a detailed list of the properties of that element.

Periodic Table of the Elements- Click on this periodic table to get all sorts of information, including history, properties, forms, uses, and costs of an element. This site was produced by the Chemical Science and Technology Division of Los Alamos National Laboratory.

WebElements- Perhaps the king of WWW periodic tables, this huge resource was created by Mark Winter of the University of Sheffield, England. Clicking on an element will bring you to an information menu that includes the element's background, chemical data, crystallography, physical data, isotopes, spectroscopy, electronic data, biological data, and geological data.

Materials Science- Learn about metals, ceramics, semiconductors, and polymers. Provided by the University of Illinois's Materials Science and Engineering Department, this site offers an introduction to classes of materials.

Chemical of the Week- Read these fact sheets to learn about the chemistry of buckyballs, autumn colors, ozone, fertilizers, and more. Professor Bassam Z. Shakhashiri distributes these fact sheets to students in his general chemistry course at the University of Wisconsin.

The Periodic Table of Comic Books- This page provides you with a comic book reference to almost any element.

17.4 EVIDENCE FOR ATOMS

How Do We Know Any of This? In this lesson from The Particle Adventure, you will learn about the experimental evidence that supports the modern theory of the atom.

17.5 MOLECULES

Molecular Models- Maintained by Eastern University, this hypermedia tutorial provides information on chemical bonds, molecular shapes, and molecular models. Downloading the Chemscape Chime plug-in allows you to create and manipulate molecular structures.

Molecule of the Month- Check out this site for a list of molecules viewable in HTML, Chime, Java, and VRML. This page is maintained by the Chemistry Department at the University of Bristol, England.

17.6 COMPOUNDS

Chemical Bonding: Introduction- This is a nice introduction to chemical bonding, including ionic and covalent compounds. This lesson comes from CHEMystery, a student-created interactive guide to chemistry.

17.7 THE ATOMIC NUCLEUS

http://physics.berea.edu/~king/Teaching/ModPhys/QM/atom.htm

Rutherford's Model of the atom:Rutherford proposed the nuclear model of the atom on the basis of his experimental results of the scattering of alpha-particles by the atoms. In his experiment alpha-particles emitted with speeds of about 2 x 107 m/s struck a thin gold foil several thousand atomic layers thick. Most of the alpha-particles pass undeflected through the foil, but some were scattered at some angle. According to Rutherford's model of the atom, almost the entire mass and the total positive charge of the atom are confined within a very small part at the center of the atom. This part is known as the nucleus of the atom and has a radius less than 10-12 cm which is small compared to the radius of the atom (approx. 10-8 cm). The electron in the atom revolves in orbits around this central core. The radii of these orbits determine the atomic radii.

Bohr Model- Learn about the Bohr model of the atom with this QuickTime movie (7.5M).

17.8 ELECTRONS IN THE ATOM

Models of Electron Orbitals- The arrangement of electrons in atoms can get quite complicated. Check out this page for 3-D (VRML) models of electron orbitals.

Millikan's Oil Drop Experiment- This QuickTime movie (9.1M) introduces Millikan's oil drop experiment, which led to the determination of electron charge.

Electron Configuration and Periodicity- How does the atomic structure of an element relate to its position in the periodic table? Find out in this lesson from ChemWeb, a student-created online chemistry course.

17.9 THE PHASES OF MATTER
