1 Section 5.3 and 5.4 Section Title: The Periodic Table New Information: Name: Period: Today we will be working in the lab to learn more about the periodic table. Your task is a web-quest. A web-quest is a guided navigation around the web that helps you answer questions about the subject. The web-quest is attached so go ahead and get started. Activity: PART 1 Periodic Table Web Quest Using the following website, answer the following questions: Click How to use the Periodic Table at the left 1. What is the atomic number? 2. What is the atomic symbol? 3. What is the atomic mass? From here, look to the right and click the link Elements Get Final Names. 4. What international body of chemists has decided the names of 6 new elements (there were members from 80 different countries? 5. What element was named by Lawrence Berkeley Laboratory? 6. What two elements did Seaborg s group produce? PART 2: NAVIGATING THE PERIODIC TABLE Directions: Using the web sites listed below and a copy of the Modern Periodic Table, answer the following questions: 1. Find the element oxygen. a. What does the 8 on the top of the chemical symbol signify? b. What does the number signify?
2 2. Find the element calcium. a. What is the chemical symbol for calcium? b. What is the atomic number for calcium? c. What is the atomic mass (weight) of calcium? 3. Find the element copper. a. What is the chemical symbol for copper? b. What is the atomic number for copper? c. What is the atomic mass (weight) for copper? Part 3: THEMES AND TRENDS ON THE PERIODIC TABLE Directions: Using the web sites listed below and a copy of the Modern Periodic Table, answer the following questions: 1. How many groups (families) are there in the Periodic Table? 2. How many elements are in your Periodic Table? 3. How many periods are there in your Periodic Table? 4. As what can the vast majority of elements in the Periodic Table be classified (metals, metalloid, nonmetal)? 5. Look at the bold line shaped like a staircase on the right side of the table. What does it divide?
3 6. a. Define metalloids? b. Provide three examples of metalloids. 7. GROUP 1: IA a. Group IA is known as. b. Why are alkali metals often stored in mineral oil? d. List two physical characteristics of alkali metals. 8. GROUP 2: IIA a. Group IIA is known as. 9. GROUPS 3 through 12 are transition metals. a. Describe the general properties of the transition metals. b. List three examples of transition metals and their uses.
4 10. GROUP 14: IVA a. Group IVA is known as b. What is the element at the top of the group? c. Find three important physical and/or chemical properties of carbon. d. Describe some of the important properties and uses of Silicon. e. List three other elements in this group and their uses. 11. GROUP 15: VA a. Group VA is known as. 12. GROUP 16: VIA a. Group VIA is known as.
