1. U NIT 1 R EVIEW Key Concepts

2. A TOMIC THEORY Be able to name historians Contribution of each of historian to atomic theory 1 to 2 significant contributions Do not need to know dates

3. E LECTRONS VS. PROTONS VS. NEUTRONS Location in atom, charge, relative mass Determining atomic number and atomic mass Isotopes and calculating average atomic mass

4. B OHR RUTHERFORD DIAGRAMS Electron configurations Be able to draw for 1 st 20 elements Can use full circle-dot method, or half circle-electron method Know what happens to diagram when electrons are added/removed from an atom to create an ion i.e. number of valence electrons and therefore Bohr Rutherford diagram will change for F (neutral) vs. F - (gain one electron, become stable)

5. P ERIODIC TABLE TRENDS Modern periodic law Period, families/groups, location of metals (alkali, alkaline earth, transition, others) non-metals (halogen, noble gases), metalloids Valence electrons, octet rule Atomic radius, IE, EA, EN – tie to reactivity # energy levels If same, # protons

6. BONDING Ionic vs. covalent vs. polar covalent Spectrum i.e. although two compounds are both ionic (i.e.  EN is > 1.6,  EN closer to 0.0 will be more ionic) Using  EN to classify bonds Physical properties of compounds with ionic vs. covalent bonds Review your lab Ionization equations and drawing Lewis structure for ionic compounds Draw Lewis structure for covalent compounds

7. VALENCE Determining valence on elements in compounds Binary compounds, tertiary/ternary compounds (polyatomic ions, oxyacids) Chemical formulas Nomenclature Stock/IUPAC Ous/ic Greek prefix
