Coll. Curriculum; essential skills are bold) Periodicity *The electron configuration of elements and their reactivity can be identified based on their position in the periodic table. *The periodic table can be used to identify metals, semimetals, nonmetals, and halogens. *The periodic table can be used to identify trends in ionization energy, electronegativity, the relative sizes of ions and atoms, and the number of electrons available for bonding. Chemical Bonds *Atoms combine to form molecules by sharing electrons to form covalent or metallic bonds or by exchanging electrons to form ionic bonds. *Salt crystals, such as NaCl, are repeating patterns of positive and negative ions held together by electrostatic attraction. *Chemical bonds between atoms in molecules such as H2, CH4, NH3, H2CCH2, N2, Cl2, and many biological molecules are covalent. *Lewis dot structures can provide models of atoms and molecules. *The shape of simple molecules and their polarity can be predicted from Lewis dot structures. *Electronegativity and ionization energy are related to bond formation.

Coll. Curriculum; essential skills are bold) Chemical Reactions and Solutions *Chemical reactions can be described by writing balanced equations. *The quantity of one mole is set by defining one mole of carbon-12 atoms to have a mass of exactly 12 grams. *One mole equals 6.02 x 1023 particles (atoms or molecules). *The molar mass of a molecule can be determined from its chemical formula and a table of atomic masses. *Hess’s law is used to calculate enthalpy change in a reaction. Students will be able to describe solutions, calculate concentrations of solutions, describe factors that affect solubility. Stoichiometry Students will be able to identify limiting reactant in a chemical reaction. Students will be able to calculate the theoretical yield of a reaction when given the amounts of the reactants (or at least the limiting reactant). Students will be able to calculate the percent yield of a chemical reaction from actual yields and data needed to calculate theoretical yield.

Coll. Curriculum; essential skills are bold) Glencoe Chemistry Matter and Change CAPT lab - for juniors who are retaking CAPT February/ March 7 March/April 8 Reaction Rates *The rate of reaction is the decrease in concentration of the reactants or the increase in concentration of products with time. *Reaction rates depend on such factors as concentration, temperature, and pressure. *A catalyst plays a role in increasing the reaction rate by changing the activation energy in a chemical reaction. *Equilibrium is established when forward and reverse reaction rates are equal. CAPT if students need to retake it Gases and Gas Laws Students will be able to explain and apply the gas laws. Students will be able to describe kinetic molecular theory to explain behavior.
