Module 5: The Periodic Table

Welcome to Module 5.  Remember, you may work at your own pace. All assignments for this module will be due (one week from the first day of the class). This module will cover some of the basic information that can be found on the periodic table. This module will feature readings and interactive periodic tables.  Make sure that each assignment is completed and turned in one week from the first day of the trimester. Look at the calendar for the exact due dates.

After completing those assignments, you will take a formative quiz in class. After turning in your formative quiz, you will receive feedback and will be advised to either move ahead or redo the module. Remember, the earlier you complete a module, the earlier you will be able take the formative quiz and receive feedback.

Part 1

View the media below and answer the questions that follow.  An answer sheet will need to be retrieved in class.

I Can Statements
- I can identify
an element's atomic mass.
- I can identify an element's atomic number.
- I can identify the number of protons in an atom of a element.
- I can determine the number of electrons in a neutral atom of an element.
- I can determine the number of neutrons in an atom of an element

Below is a link of a standard periodic table. It is similar to the periodic table in the back of your chemistry book. Click there and scan it over. Do you know what all those numbers mean? Do you know which elements are in families?
The Periodic Table

The website and video below have some really good basic information on the periodic table. Read it, take notes on it, and use it to help answer the questions that follow. Pay attention to the formulas it provides.

Finish the following statements:
1. The atomic number is equal to the number of _______________.

2. O (Oxygen) has an atomic number of _______________.

3. Oxygen has ________________ protons.

4. Neutral atoms have no charge. Therefore, the number of protons is the same as the number of _____________.

5. A neutral atom of Helium (He) has as an atomic number of ______________, ___________ protons, and ____________electrons.

6. The atomic weight (also known as atomic mass) of C (Carbon) is___________ (make sure to round it to the nearest whole number)

****The # of Neutrons= Atomic Number - Atomic Mass

7.The element with an atomic number of 16 is _______________. This element has an atomic mass/weight  of ____________ (round it to the nearest whole number).

8. How many neutrons does Sulfur (S) have?

9. Fill out the table below:
Element Name
Atomic Number
Atomic Mass
# Protons+
# Electrons-
a.  Aluminum (Al)


 Part 2

View the media below and answer the questions that follow.  An answer sheet will need to be retrieved in class.

I Can Statements
- I can i
dentify metals from non-metals.
-I can identify the common properties of certain families (groups) of elements.
- I can identify the location of families(groups) on the periodic table
- I can identify that families (groups) are arranged in columns/vertically/up and down.

View the following periodic tables.

Periodic Table 1  Click on an element to learn more about it

Periodic Table 2  Click on an element and watch a video of some British chemists playing with chemicals

Dynamic Periodic Table 
This might be the greatest periodic table on the internet. Move your mouse around check it all out. Click on an element or family/group number to learn more.

10. Identify the following elements as metals or non-metals (make sure to look on the periodic table, don't just guess based on what you think you know)
a.  Potassium (K)
b. Calcium (Ca)
c. Sodium (Na)
d. Krypton (Kr)
e. Chlorine (Cl)
f. Mercury (Hg)

12. What do the Noble gases have in common? Name at least 3 things.

13. Why do you think the Noble gases are considered a group/family?

14. Fluorine, Chlorine, Bromine, and Iodine are all part of the __________________ family/group.

3 new things you learned about those elements.

a. Helium

b. Hydrogen
c. Carbon
