Chapter 1Science Skills

•Branches of Science•Scientific Method (Steps)

•Scientific Laws •Scientific Models

•Units of Measurement ( Metric to metric Conversions)

•Organizing Data ( Direct & Inverse Proportions, Independent & Dependent Variables,

Equations of Lines)

Chapter 2Classifying Matter

• Pure substances• Elements• Compounds• Mixtures• Solutions, Colloids, Suspensions• Physical & Chemical Properties• Physical & Chemical Changes• Techniques for Separating Mixtures

Chapter 3States of Matter

• States of Matter (solids, liquids and gases)

• Kinetic Theory (recall molecular motion and its relation to temperature and phase)

• Behavior of Gases, Liquids, and Solids• Phase Changes ( melting, freezing, condensation,

vaporization, sublimation, deposition, changes in temperature during and between phase changes)

Chapter 4Atomic Structure

• The Greek’s Model of the Atom (Democritus)

• John Dalton’s Atomic Theory ( his representation of the atom)

• J.J. Thomson’s Atomic Model ( his atomic model and the evidence for subatomic particles)

• Rutherford’s Model of the Atom ( his atomic model, the gold foil experiment, the discovery of the nucleus)

• Neils Bohr’s Atomic Model ( his representation of the atom, what happens to the electron as it transfers energy levels)

Chapter 4Atomic Structure

• Atomic Number, Mass Number ( How they are determined, what they represent)

• Properties of Subatomic Particles ( Charges and masses of the Proton, Neutron, and Electron, who was Chadwick?)

• The Electron Cloud Model of the Atom ( what is an electron cloud)

• Atomic Orbitals ( What is the maximum number of electrons in each energy level?)

Chapter 5The Periodic Table

• Mendeleev’s Periodic Table ( on what basis was his periodic table organized, who was Moseley and how was his periodic table organized)

• The Periodic Law ( what are groups, periods, and families)

• Atomic Mass (how is it calculated)

• Classes of Metals (differentiate between the properties of metals, non-metals, and metalloids)

• Variation Across a Period ( general periodic trends such as where are the most reactive metals, non-metals, and metalloids)

• Valence Electrons ( how do these effect the properties of the elements, where are the Noble Gases, Halogens, Alkaline Earth Metals, and Alkali Metals)

Chapter 6Chemical Bonds

• Stable Electron Configurations• Ionic Bonds (definition, what are anions, and cations, what is

ionization energy)

• Covalent Bonds (definition)

• Describing Ionic Compounds ( name common ions and polyatomic ions, writing formulas for ionic compounds)

Chapter 7Chemical Reactions

• Chemical Equations (identify the products and reactants of an equation)

• Balancing Equations (mass balance using coefficients)

• Classifying Reactions (identify synthesis, decomposition, single replacement, and double replacement reactions)

Chapter 8Acids and Bases

• What is an acid?• What is a base?• What occurs during a neutralization reaction?

What are the products of such a reaction?• What is a buffer, and indicator, a salt?• Describe strong vs. weak acids and bases.• How does concentration differ from strength?• What does pH indicate?• What are Hydronium ions?• Write balanced equations using coefficients for

various acid-base reactions.
