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?
