Lesson: Ionic Bonding Chemistry

Students will be able to

• recall the octet rule and its relation to the valency of an atom,
• recall the formation of cations and anions from the loss or gain of electrons,
• describe how ionic bonding involves the transfer of electrons between atoms,
• describe how the electrostatic attraction between ions of opposite charges gives rise to ionic bonding,
• draw Lewis structures to show ionic structures and bonds,
• describe the physical properties of ionic structures and how these arise from their bonding,
• recognize that ionic compounds have a regular lattice structure, using sodium chloride as an example,
• recognize the 2D and 3D structures of ionic compounds, using sodium chloride as an example,
• identify the formula unit for an ionic compound.
