1 VOCABULARY define the following terms: Unit 1 Study Guide Honors Chem 1) Electron configuration- 2) Effective nuclear charge 3) Isotope 4) Ion 5) Anion 6) Cation - 7) Isoelectronic - 8) Halogens 9) Electronegativity - 10) Electron affinity 11) Ionization energy 12) Atomic radius- 13) Valence electrons- 14) Energy level 15) Orbital- 16) Intermolecular forces 17) Intramolecular forces- 18) Excited state 19) Ground state - 20) Orbital diagram 21) Periodic law 22) Covalent bond- 23) Polar bond- 24) Nonpolar bond 25) Ionic bond 26) Wavelength- 27) Frequency- 55 multi choice Q Hints: - study old quizzes -study practice worksheets & notes -study for understanding, not memorization BOND TYPE A. How do you know how many valence electrons an element has? B. How do you know what the ionic charge is for any element on the periodic table? C. How is an ionic bond different then a covalent bond? D. How can you distinguish an ionic compound from a covalent compound? E. What are the rules for naming ionic molecules? Naming covalent molecules? F. What are the rules for writing formulas for ionic compounds? Covalent compounds? G. Rank the bond types in order of strongest to weakest: ionic, nonpolar, metallic and polar.

2 H. How can you tell what of bond forms between two atoms? I. Explain how intermolecular forces are different then intramolecular forces? Why are both important? J. Rank the 4 bond types in order of highest melting and boiling points to lowest melting and boiling points. Explain why some molecules require more energy to melt/boil then others. K. Volatility is the ability of a substance to evaporate rapidly. For example, rubbing alcohol spilled on the bathroom counter will evaporate faster (more volatile) then water spilled on the bathroom counter. As vapor pressure increases, volatility increases. What happens to boiling point? ATOMIC STRUCTURE A. COMPLETE THE CHART. Subatomic particle Charge Relative size B. A PICTURE OF AN ION (label the nuclear charge, protons, neutrons, and electrons) C. DRAW A PICTURE OF TWO ATOMS THAT ARE ISOTOPES (label the protons, neutrons, and electrons) How are isotopes different? How are isotopes the same?

3 D. What is the relationship between wavelength and amount of energy released? E. What is the formula relating frequency and wavelength for light? F. Write the ground state and excited state electron configuration for phosphorous. G. Write the electron configuration and noble gas abbreviation, and orbital diagram for the following: i) Calcium ii) Neon iii) Tungsten iv) Seaborgium

4 PERIODIC TABLE TRENDS A. Color or label the following PERIODIC TABLE FAMILIES on the periodic table: -halogens -alkali metals -alkaline earth metals -noble gasses -transition metals -increasing reactivity B. Metal v. Nonmetal COLOR OR LABEL THE FOLLOWING -METALS -NONMETALS -METALLOIDS C. Trends LABEL THE FOLLOWING ON THE PERIODIC TABLE -increasing atomic radius -increasing effective nuclear charge -increasing ionization energy -increasing electron affinity -increasing electronegativity -valence electrons -ionic charge
