Product Description
The following standards are assessed on this exam:
C10. I can differentiate between different types of bonds
I can distinguish among ionic, molecular covalent, and metallic substances, given their properties and/or chemical formulas.
I can describe what is happening to the valence electrons in each type of bond
I can name simple covalent molecules when given chemical formulas.

C11: I can explain how atoms form covalent molecules
I can use the periodic table to determine the number of valence electrons in an atom and draw Lewis dot symbols
I can distinguish between molecular formulas, structural formulas, and Lewis Dot structures
I can diagram covalently bonded molecules using Lewis dot structures and structural formulas
I can explain how covalent bonds are formed using the octet rule

C12: I can explain electronegativity and use it to predict the polarity of a molecule
I can explain the relationship between an element’s position on the periodic table and its electronegativity.
I can use electronegativity to explain the difference between polar covalent, nonpolar covalent bonds, and ionic bonds.
I can use the Pauling Electronegativity Scale to determine whether a bond will be polar covalent, nonpolar covalent, or ionic.

C13: I can use polarity to describe properties of a substance.
I can predict the general direction and strength of a dipole for any two bonded atoms on the periodic table.
I can determine the partial charges on any atom in a covalent molecule
I can assess a molecule for symmetry, determine whether it is likely to be polar, and describe how it will behave.
I can describe intermolecular forces and identify how intermolecular forces in polar and nonpolar substances affects their properties (e.g., solubility, smell, attraction to a charged wand, etc).
