Goal:
Use electronegativity to predict whether atoms will form ionic or covalent (polar or nonpolar) bonds.

ACT Practice
You have 10 minutes to answer the ACT practice questions. After we will debrief and discuss challenges and strategies.

Notes
Create a new journal entry entitled "Bond Types." Answer the questions:

• Why do atoms bond?
• Define the following bonds and explain when they occur. 
• Ionic Bond
• Polar Covalent Bond
• Nonpolar Covalent Bond

Practice

Make a copy of this worksheet and complete in class. 

Journal

In your journal, answer the following questions:

1. Identify the metallic character of magnesium and chlorine.
2. Calculate the electronegativity difference between magnesium and chlorine. 
3. Write a CER explaining whether you think MgCl2 is ionic, nonpolar covalent, or polar covalent. Use the answers to questions 1 and 2 as evidence.
