Chapter Review Notes
The end of chapter Key Terms, Key Skill and Concepts, and Key Equations and Relations are as good an overview or review sheet as I could make for you.  The only thing better would be for you to make your own review sheet (See below).  In each chapter review section there are a few things that you are either not responsible for or that need clarification.  I include that information for each chapter below.
Chapter

Chapter 1
You are not responsible for all the Key Terms.  The ones to ignore are: anion, cation, ionic compound and metalloid.
You are not responsible for any of these terms as they occur in other parts of the review material either.

Chapter 2
There is one missing Key Term: accelerator (p. 74)
In section 2.7 you are not responsible for the term: roentgen.

Chapter 3
Remember that you are only responsible for the principle quantum number n, but may want to learn the others, if it helps you keep things straight.

You are responsible for the equation:detaE = Efinal-Einitial and the fact that when the value is negative you have an emission process and positive implies absorption of light.  You should be able to stick in any random expression for the values of Ef and Ei.  You are not responsible for particular versions of this equation like 3.1, 3.4, 3.6 or 3.8, but should be able to generate them from expressions for a particular energy level. For example, if you are given En = (-2.18 x 10-18 J)/n2, which is equation 3.6, you should be able to generate equation 3.8 from it.

You are not responsible for the Boltzmann distribution (eq. 3.10) although it does explain why we see only certain missing (absorption) lines in the spectra of stars.

The form of the deBroglie relation you are responsible for is: deBroglie equation.

Chapter 4
Key Terms: you are not repsonsible for remembering the names of the laws of definite proportions and multiple proportions, but do need to understand the underlying concepts.

Section 4.3: You should know that the endings -ous and -ic on positive ions tell you somthing about  the charge on the positive ion.  However, you would have to memorize for each metal what the possible (+) charges are to make use of this naming scheme.  Thus you are not responsible for knowing things like cupric, cuprous, ferric and ferrous.  If you see them you will know to look up what they mean in the future.  All the other naming information is systematic and you are expected to be able to use it.

Chapter 5
Skipped sections: 5.5, 5.8 & 5.9
You are NOT responsible for the following key terms: electrochemical cell, electrolysis, electrolytic cell, equivalence point, half-reaction, ion-exchange reaction, oxidation, oxidation number, oxidizing agent, redox reaction, reducing agent, reduction, standard solution, titration, voltaic cell.

The key terms net ionic equation and spectator ion are also found on page 256.

Additions to Key Skills and Concepts
Section 5.2: be able to convert between molarity and ppm, ppb or ppt by mass.
Section 5.4: be able to convert between molality and molarity.
Section 5.7: the solubility rules you are responsible for are that group 1 and nitrate salts are soluble.  Everything else should be looked up.

Chapter 6
Addition:  Be able to use the bond-type triangle to predict the kind of bonding that would be observed between two atoms.

Chapter 7
Skip section 7.5.
You are not responsible for the key term electron-spin resonance (ESR).
You are not responsible for calculations of dipole moments that require using trigonometry.

Additions to Key Skills and Concepts:
You should understand how the hybrid orbital model explains double bonds.
You should be able to see the difference between cis- and trans- isomers of double bonded species.

Chapter 8
The ideal gas law, PV=nRT, MUST BE MEMORIZED.  It will not be provided on the exam.  The value for the gas constant, R, will be provided.  Since Boyle's Law and Charle's Law can be derived from the ideal gas law they will not be provided either.  Other relations except for 8.8 will be provided if needed.

Key equation 8.8 can be derived as follows by assuming that the number (moles) of gas molecules, n, is constant:

P1V1 = nRT1 => P1V1/T1 = nR.                P2V2 = nRT2 => P2V2/T2 = nR

Since they both = nR this implies that P1V1/T1 = P2V2/T2.

Add the equation for molar kinetic energy to the key equations and relations section 8.7:
KE(molar) = (1/2)(molar mass)urms2.

Chapter 9
In the Key Equations section 9.2 add the equation: U = k(Q1Q2/d)

Chapter 10
Key Terms section.  You are NOT responsible for the term: hexagonal closest packing.

Key Skills and Concepts section. 
Section 10.1: You are NOT responsible for calculations using Bragg's law.
Section 10.3: You are NOT responsible for describing the differences between ccp, hcp and simple cubic packing.  You should be able to calculate a density given the radius of the species in the unit cell and the unit cell type and determine which unit cell type is consistent with a measured density knowing the atomic radius.
Section 10.7 first line: "continuing" should be "containing".

Key Equations and Relations section.  Add the equations for the volumes of the cubic unit cells:
Vsimple cubic = Vcubic = 8r3     V(bcc) = (4^3)(3^(3/2))(r^3)          V(fcc) = (16)(2^(1/2))(r^3)

Making Your Own Review Sheets
The process of making a review sheet helps to set concepts in your mind.  It will not do you much good if you do it by copying the review material at the end of the chapter.  The most effective way to make the review sheet is to go through the chapter looking for key terms, concepts, equations and relations.  Many of these items will be in bold face, italics or set off in some other way.  The headings for sections are also useful guides to key ideas you should be familiar with.  Then go through the suggested homework problems and make groups of similar types of problems.  Try to come up with a label or description for each group.

I hope some of you find these suggestions useful.
