Test Study Guide: Chapters 3, 4, 7, and 8
Chapters 3, 4 (except 4.5), 7, and 8 (only 8.1, 8.6-8.7) on Tuesday, October 13, 2009
[Note: Calculators are not allowed. You will be provided with a copy of the periodic table and important ions.]
KNOW THE FOLLOWING CONCEPTS:
o different models of the atomic leading up to the current quantum model
o Dalton’s atomic theory
o compare and contrast between elements, atoms, molecules, compounds, and ions
o types of subatomic particles and their relative masses and locations in an atom
o relationship between the nucleus and the mass and size of an atom
o difference between a covalent bond and an ionic bond
o how to interpret the periodic table
o the difference between groups and periods on the periodic table
o characteristics of elements based on the periodic table
o ion charges based on the periodic table
o identify the different types of electrolytes (strong, weak, and non)
o identify metals, metalloids, and nonmetals based on the periodic table
o identify Groups 1A, 2A, 7A, and 8A based on group name
o diatomic elements
o the types of chemical reactions, e.g. decomposition, synthesis, etc.
o predicting the products of a chemical reaction
o law of conservation of mass
o valence electrons and their significance
o Lewis electron dot structures
BE ABLE TO ANSWER PROBLEMS INVOLVING:
o identifying the numbers of protons, neutrons, and electrons based on atomic number, atomic mass, and charge
o write chemical equations how ions (either cations or anions) are made
o how to write chemical formulas of compounds (both ionic and covalent)
o how to write and balance chemical reactions of any of the 5 main types (combustion, synthesis, decomposition, single-replacement, and double-replacement)
o density
o Lewis electron dot structures of elements and compounds
o any variation of the above types of problems may show up on the quiz
