ESSENTIAL UNIT 3 (E03) (Chemical Bonding and Naming)
Unit Statement: This unit presents and explains the interactions between atoms, the rules used to name chemical compounds, and the structure of metals.
Essential Outcomes: (Must be Assessed)
1. The Student Will recognize stable electron configurations, relate them to the periodic table, and predict an element’s chemical properties using number of valence electrons and electron dot diagrams. (p. 158 – 160)
2. TSW describe how an ionic bond is formed and how ionization energy affects this process. (p. 160 – 161)
3. TSW predict the composition of an ionic compound from its chemical formula and relate the properties of ionic compounds to the structure of crystal lattices. (p. 161 – 164)
4. TSW describe how covalent compounds are formed including the attractions that keep atoms together in molecule. (p. 165 – 167)
5. TSW explain how a molecule can be either polar or non-polar and compare the attractions between polar and nonpolar molecules. (p. 167 – 169)
6. TSW recognize and describe binary ionic compounds, metals with multiple ions and polyatomic ions. (p. 170 – 173)
7. TSW differentiate between an atom, an ion and a polyatomic ion, and memorize these common polyatomic ions and their charges: PO4, SO4, CO3, NO3, NH4, OH, and HCO3. (p. 171 – 172)
8. TSW name and determine chemical formulas for ionic and molecular compounds and predict the composition of a compound from its chemical formula. (p. 173 – 175)
9. TSW describe the structure and strength of bonds in metals, relate the properties of metals to this structure, and demonstrate how the composition of an alloy affects its properties. (p. 176 – 181)
10. TSW apply the scientific method in a variety of ways with a focus on one or two areas of the process. (Appendix in Curriculum Guide)
