Unit 2 Test

SC2 Obtain, evaluate, and communicate information about the chemical and physical properties of matter resulting from the ability of atoms to form bonds.

SC2.d Develop and use models to evaluate bonding configurations from nonpolar covalent to ionic bonding.

• I can predict bond type as nonpolar covalent, covalent, or ionic based on whether elements that are bonding are metals, nonmetals, or metalloids. (Reasoning)

• I can identify bond type as nonpolar covalent, covalent, or ionic based on the electronegative difference between two elements.(Knowledge)

• I can identify bonding patterns among similar elements based on their location on the periodic table. (Knowledge)

• I can describe what happens to the electrons, draw and describe Lewis dot structures, predict properties of substance, and names of compounds based on the elements present in the substance . (Reasoning)

• I can evaluate models of covalent and ionic bonding. (Reasoning)

• I can differentiate between covalent and ionic substances. (Reasoning)

• I can explain the behavior of covalent and ionic substances based on their bonding. (Reasoning)

• I can draw electron dot structures for elements, binary ionic, and covalent compounds. (Product)

SC2.e Ask questions about chemical names to identify patterns in IUPAC nomenclature in order to predict chemical names for ionic (binary and ternary), acidic, and inorganic covalent compounds.

• I can label metals, nonmetals, and metalloids in compounds. (Knowledge)

• I can recognize and classify covalent, ionic, and acidic compounds. (Knowledge)
