Chemistry Final Review Sheet

Chapter 2 – Data analysis (7 questions) • Metric prefixes and how their relative comparisons: kilo-, deci-, centi-, milli- • Scientific notation • Significant figures • Conversion factor • % by mass • % error

Chapter 3 – Matter- Properties and Changes (8 questions) • Physical properties and Chemical properties AND Physical and Chemical Changes • States of matter and their general properties • Law of conservation of mass • Elements, compounds, Molecules • Chapter 4 – Structure of the atom (8 questions) • Discoveries of subatomic particles (proton-neutron-electron)- Scientist- know the general overview of experiments • Charge, location, general mass considerations of the proton, neutron, electron • Atomic number verse mass number- what are they? What particles are involved? • Isotopes- what are they?

Chapter 5 – Electrons in Atoms (11 questions) • How does the spectrum relate to the energy of an electron? • What is an electron cloud verse atomic orbital? • Electron Configuration and energy associated with where it is on the configuration • Ground state verse excited state and when does it gain energy verse release energy (light). • Octet rule and valence electrons • Valence electrons and electron configuration. • Rules to filling out electron configuration

Chapter 6-7 – The periodic table and periodic law • (8 questions) and Elemental Families (7 questions) • Metals, metalloids, nonmetals- properties and locations • Cations verses anions- formation, charge, and size (compared with parent atom and each other). • Given a electron configuration- locate with period/group • Trends Ionization, electronegativity, size of atom and size of ion • Energy levels and periods • Transitional elements and synthetics • 4 major families- how do they differ in reactivity, periodic trends, charges and chem./physical properties.

Chapter 8 – Ionic compounds (15 questions) • General ionic bonding- what is happening to cation and anion-electron wise and charge? • Balance charges using subscript AND Using the subscript in formulas as clues to charges on ions. • Name to formula AND formula to names- KNOW transitional roman numerals and when to use them. • Polyatomic ions- what are they? How to use the parentheses and read common ion sheet. • Properties of ionic substances. • Lattice energy

Chapter 9 – Covalent compounds (17 questions) • General covalent bonding- What is it? What is happening to electrons? Double/Triple bonds and differences • Know your prefixes for naming molecules. Use prefixes from formula to provide the name. • VSEPR model descriptions of bonds and lone pairs to provide shape name. • Polarity (Electronegativity) polar vs. non-polar • Lewis dot structures • Chapter 10- Chemical Reactions (14 questions) • KNOW your types of reactions • Balance different equations • Predict products from clues provided by the reactants

Review Game • Pair up and sit next to your partner. • Do this NOW! Sit next to each other • NOT in lab area. • NO SINGLES!!!!! OR TRIPLES!!! • You and your partner will get a numbered piece of paper with 2 questions on it.

Review Game • Put your names on the Review squares sheet. • Right Now- Answer your questions on the Review square sheet with partner. • When the wheel spins, whatever number comes up decides whose question will go. • Each person answers a question. • The audience will write down answers on Review squares sheet.
