Getting To Know the Periodic Table
Getting To Know the Periodic Table
Objective: To be able to use the periodic table to identify and classify elements and to use the periodic table to predict the behavior of elements
Procedure:
1. Color each of the following groups a different/contrasting color (be sure to make a key):
color hydrogen light pink
Group 1 alkali metals
Group 2 alkaline earth metal
Group 3-12 (collectively) transition metals
Group 17 halogens
Group 18 Noble gases
bottom rows Actinide Series
Lathanide Series
Metalloids (elements that have properties of metals and nonmetals)
2. Write a g in the boxes of the elements that exist as a gas at ordinary conditions.
3. Write a L in the boxes of the elements that exist as a liquid at ordinary conditions.
4. Outline the s, p, d, and f blocks different colors (using markers may help)
Things to know:
1. Period number represent the quantum energy levels that each element in that row contains
2. Group A elements—roman numerals at the top of each column represent the number of valence electrons in that group. Does not work for B groups.
Directions: Answer the following questions on your own paper.
1. Define the following terms: periodic table, periodic law, group, family, period, metal, nonmetal, and metalloids.
2. Which groups are in the s-block? d-block? p-block? f-block?
3. Describe the physical properties and the chemical properties of each of the following groups:
| |Family Name |physical properties |chemical properties |
|Group 1 | | | |
|Group 2 | | | |
|Groups 3-12 | | | |
|Group 17 | | | |
|Group 18 | | | |
4. Describe the properties of metalloids.
List the metalloids.
5. Name an alkali metal.
6. Name a noble gas.
7. Which family ends with the electron configuration ns2?
8. Which family ends with the electron configuration ns2np5?
9. Which group has 1 valence electron?
10. Which group has 8 valance electrons?
11. Name an element in period 4.
12. Name an element in group 15.
13. Name the element in group 15 and period 3.
14. What element has 2 valence electrons and 5 quantum energy levels?
15. What are some unique details about hydrogen and helium in terms of their placement on periodic table?
