### 1: Matter and Its Interactions

#### 3: Use the periodic table as a systematic representation to predict properties of elements based on their valence electron arrangement.

3.a: Analyze data such as physical properties to explain periodic trends of the elements, including metal/nonmetal/metalloid behavior, electrical/heat conductivity, electronegativity and electron affinity, ionization energy, and atomic-covalent/ionic radii and how they relate to position in the periodic table.

3.b: Develop and use models (e.g., Lewis dot, 3-D ball-and-stick, space-filling, valence-shell electron-pair repulsion [VSEPR]) to predict the type of bonding and shape of simple compounds.

3.c: Use the periodic table as a model to derive formulas and names of ionic and covalent compounds.

#### 5: Plan and conduct investigations to demonstrate different types of simple chemical reactions based on valence electron arrangements of the reactants and determine the quantity of products and reactants.

5.a: Use mathematics and computational thinking to represent the ratio of reactants and products in terms of masses, molecules and moles.

5.b: Use mathematics and computational thinking to support the claim that atoms, and therefore mass, are conserved during a chemical reaction.

#### 6: Use mathematics and computational thinking to express the concentrations of solutions quantitatively using molarity.

6.b: Analyze and interpret data to explain effects of temperature on the solubility of solid, liquid, and gaseous solutes in a solvent and the effects of pressure on the solubility of gaseous solutes.

### 3: Energy

#### 11: Construct an explanation that describes how the release or absorption of energy from a system depends upon changes in the components of the system.

11.a: Develop a model to illustrate how the changes in total bond energy determine whether a chemical reaction is endothermic or exothermic.

11.b: Plan and conduct an investigation that demonstrates the transfer of thermal energy in a closed system (e.g., using heat capacities of two components of differing temperatures).
