Week: 19
Topic: Chemical Interactions: Chemical Bonding (Ionic Bonds)
Students will be able to:
Describe ions and explain how they form bonds.
Explain how the formulas and names of ionic compounds are written.
Identify the properties of ionic compounds.
Essential Question:
Two atoms are talking together.
Atom #1: I am about to lose an electron!
Atom #2: Are you sure?
Atom #1: I’m positive.
This week the 8th graders will work with the outer shell of elements and create ionic bonds to understand the concept of ionization. They will see how these reactions occur between metals and nonmetals.
Key Terms:
