1. Chemistry I Objectives Unit III Chapter 7
I.   Explain ion formation as it relates to the number of valence
electrons in an atom and be able to predict what ion is formed
by all the representative elements.
II. State the octet rule and describe the characteristics of ionic
bonds. (metals to nonmetals)
III.   Draw electron dot structures of atoms to show ionic bonding.
IV. Identify the coordination number for different unit cells such
as cubic, tetragonal, or hexagonal
Define the term formula unit and explain why it is the smallest
particle in an ionic compound.
VI. Discuss the properties of ionic compounds as it relates to their
bonding.
VII. Explain how metallic bonding accounts for the properties of
metals such as malleability, ductility, and conductivity.
VIII. Explain the importance of alloys and how they relate to the
arrangement of atoms in a metal

2. Chemistry I Objectives Unit III Chapter 8
I.   Differentiate between molecular formulas and an ionic formulas
and explain what information they provide.
II. Explain how covalent bond is different than an ionic bond
and how a coordinate covalent bond is different than a
regular covalent bond.
III. Apply the octet rule to draw models of molecules using
electron dot structures and explain exceptions to the rule.
IV.   Identify and distinguish polar, and nonpolar covalent bonds,
and ionic bonds based on the electronegativity of the atoms.

VI.  Be able to identify the basic shapes of molecules and
predict the geometry of small molecules from their formulas.
