Journal Entry:

A gold ring is made up of individual gold atoms.

1.What keeps the atoms together? Why don't they break apart from one another? 2.What parts of the atom do you think are responsible for keeping the atoms together in a solid.

Learning Intentions

• We will learn how to define a chemical bond and learn the four basic models of chemical bonds.

• We will learn how to use chemical formulas to sorts substance into bonding categories.

• We will learn how to predict properties of substance based on its chemical formula and model of bonding .

Closing Task:

You can identify type of bonding in an unknown substance based on properties.

Content Standards being covered:

Students can use the periodic table as a model to predict the relative properties of elements based on the patterns of electrons in the outermost energy level of atoms.

Student understands why bonding occurs between atoms, what types of bonds form when different elements interact, how the bonds form and properties that arise as result of the bond forming.
