Journal Entry:

Discuss conductivity and melting point of ionic compounds and relate to structure.

Learning Intentions

• You will learn ionic compound properties based on the structure of an ionic compound and be able to create a comic strip that demonstrates these properties.

• You will learn structure of covalent bonding and how to draw Lewis structures to represent.

• You will learn properties of covalent bonding based on the structure.

Closing Task:

You can draw the Lewis structure for a molecular compound that is covalently bonded.

Content Standards being covered:

Students can predict properties of substances based on their chemical formulas, and provide explanations of their properties based on  particle views. (LO 2.1)

Students can predict the type of bonding present between two atoms in a binary compound based on position in the periodic table and the electronegativity of the elements. (LO 2.17)

Ionic bonding results from the net attraction between oppositely charged ions, closely packed together in a crystal lattice. (EK 2.C.2)

Ionic solids have high melting points, are brittle, and conduct electricity only when molten or in solution. (EK 2.D.1)
