Chemistry Learning Targets Unit 3: Ionic Bonding Essential Questions: How can we use patterns to predict chemical behavior? How does the structure of the atom impact its behavior? Learning Goal 1: I can identify the properties of an ionic compound. Complex content: I can describe the physical properties of ionic compounds. Simpler content: I know that an ionic compound is composed of a cation and an anion. Learning Goal 2: I can determine the number of valence electrons in an element or ion Complex content: I can identify the number of valence electrons for an ion based on the octet rule. I can draw the Lewis dot structure for an element or ion. Simpler content: I can use the group number to determine the number of valence electrons for a neutral element. 4 3 2 (along with 3.0 skills) (along with 2.0 skills) (along with 1.0 skills) I can devise a procedure with 3 or more steps to test if a compound is ionic. I can select an ionic compound from a list or based on a description. I can explain the importance of valence electrons and how they are related to charge. I can identify the number of valence electrons for an ion based on the octet rule. I can draw the Lewis dot structure for an element or ion. I can list the physical properties of an ionic compound. 1 I can define cation and anion.
