  1. Unit 3 Quizzes

  2. 10.11 • What is the equation to find the charge of an atom/ion? • Name 2 elements that “want” to lose electrons. • Name 2 elements that “want” to gain electrons. • Name an element that wants to share electrons. • After an Oxygen atom gains or loses electrons, what is its charge?

  3. Unit 3 Review Project Topics -8 is great/full valence shells -types of bonds and how they work -ionic compounds: bonding, naming, and properties -covalent bonds and molecular compounds -Lewis structures -biochemistry & organic molecules

  4. 10.15 • What kinds of elements are in metallic bonds? • What is happening to the electrons in metallic bonds? • What kinds of elements are in covalent bonds? • What kinds of elements are in ionic bonds? • What happens to the electrons in an ionic bond?

  5. Open Note Group Quiz! Use your lab group to complete the front of page 34. I will collect and grade 1 per group. Put all of your group members’ names on your paper :D
