Chemistry 06：Intramolecular Forces

Do you know how atoms are connected to form molecules? In this content, we will look at ways atoms bond, including ionic, covalent bonding, and bond polarity.

Activities:

I.  Ionic Bonding:

• Review the concept of ionic bonding by drawing out lewis symbols of Na and Cl to explain ionic bond in NaCl.
• Students may draw out lewis symbol of each element to understand how they are ionically bonded in each molecule.

II. Covalent Bonding:

• Explain the concept of covalent bond by drawing out lewis structure of each molecule.
• Explain how single, double, and triple bond works by drawing out lewis structures of each molecule.
• Students may draw out lewis symbol of each element to understand how they are covalently bonded in each molecule.

III. Bond Polarity:

• Explain the concept of bond polarity and draw out the difference between nonpolar covalent and covalent bonds.
• Show the relationship of electronegativity with nonpolar covalent, polar covalent, and ionic bond.
• 💡 Originals Content Tip: Use the “polls” feature and ask students to input their answers to the problems. Then, view and discuss the class result.
