Journal Entry:

The atomic mass of silver is 107.9 amu. The atomic mass of gold is 197.0 amu. Where would you place these elements on the periodic table you created in Lesson 9 yesterday? Explain your reasoning

Learning Intentions

• We will learn how to use the periodic table to identify elements that are metals, nonmetals, metalloids, alkali metals, alkaline earth metals, transition elements, halogen and noble gases.

• We will learn the general properties of elements that are periodic.

Closing Task:

You can predict the general properties of an element based on its location on the periodic table and identify elements that will exhibit similar chemical behavior.

Content Standards being covered:

Student 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.
