Journal Entry:

If there are two isotopes of Nitrogen, Nitrogen-14 and Nitrogen-15, which isotope is most abundant in nature and how do you know?

Learning Intentions

• We will learn what types of questions will be on the unit summative assessment.

• We will learn how to properly prepare for the unit summative assessment

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

Closing Task:

You can properly prepare for our unit summative assessment

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.
