Unit 5 - Atomic Structure and the Periodic Table

Now that we have learned about the basic composition and properties of matter, we are going to take a closer look at the fundamental particles that make up all matter -- atoms. We will first examine the subatomic particles that make up atoms and briefly review the history of the model of the atom. Next, we will compare and contrast the structure of neutral atoms, ions, and isotopes. Throughout the unit we will utilize and learn the usefulness of a fundamental tool of chemistry -- the periodic table -- and how it can be used to predict the structure as well as the physical and chemical properties of elements.

Instruction will be a mix of direct instruction supplemented by short video lessons, power point presentations, worksheets and a class activity. A GOOD COPY OF A PERIODIC TABLE IS REQUIRED. Click here to see a good periodic table. It is in color. Print a copy and keep it handy.

SPS2: Students will investigate the current understanding of the atom.

SPS4: Students will investigate the arrangement of the Periodic Table to
a. Determine the trends of the following:

• number of valence electrons
• types of ions formed by representative elements
• location of metals, nonmetals, and metalloids

SPS4b. Use the Periodic Table to predict the above properties for representative elements.

Assignment 1: Mini-lecture. The Periodic Table and the Structure of Atoms. Take notes, then complete the exercises on the Atoms and the Periodic Table worksheet. (Click here to see worksheet).

The following videos will help you review what you learned.





Assignment 2: Project -- Periodic Table Basics. This is a class activity. You will work together in small groups of 3-4 students to make a poster and then answer questions about the Periodic Table. Follow the instructions on the handout (provided).

Assignment 4: Mini-lecture -- Metals, Non-metals, Metelloids and Noble Gases. Take notes and participate in class discussion.


Assignment 5: Mini-lecture -- Neutral Atoms, Ions, and Isotopes. Take notes. Participate in class discussion.

Assignment 6: Ionic vs. Covalent Bonds and the Periodic Table. -- mini-lecture. Take notes. Participate in class discussion.

Quiz: Atoms and the Periodic Table. Quiz requires being able to use the Periodic Table to answer questions about the structure of the atom, valence electrons, and the formation of neutral atoms, ions, and isotopes. It will also include predicting the chemical properties an atom, including what type of bonds it can form, based on its position in the Periodic Table.
