The Periodic Table

Fill in the blanks with words from the box.

| |All matter is composed of various elements. An _________________ is a form of matter that is composed of a single |

| |type of _________________. In 1869, Dmitri _________________ created the _________________ table to group the |

|[pic] |elements. Periodic tables usually show the element name, the element _________________, and the atomic number. |

| | |

|Calcium: an element on the periodic | |

|table with atomic number 20. | |

|As you go across a row from left to right, the _________________ of the element increases. The atomic number is the same as the number of protons in the |

|nucleus of an atom. As well, elements that have similar _________________ are placed in the same _________________. For example, copper, silver, and |

|_________________ all have similar properties and are all placed in column eleven of the periodic table. Elements on the left side of the table tend to |

|have properties of _________________ and elements on the right side of the table tend to have properties of _________________. Elements in column 18, the |

|last column on the left, are _________________ gases, which are gases that generally do not react with other elements. |

| | |[pic] |

| |Neon is one of the inert gases, which are located in column | |

| |18 of the periodic table. Inert gases do not normally react | |

| |with other elements. | |

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. Number the groups.

2. Number the periods

3. Draw a heavy lack line between the metals and nonmetals.

4. Write the name of each of the following groups above the number:

Group 1 alkali metals

Group 2 alkaline earth metal

Group 3-12 (collectively) transition metals

Group 16 chalcogens

Group 17 halogens

Group 18 Noble gases

5. Write the names of the two rows at the bottom of the chart: lanthanides and actinides

6. Write the symbol of each element that exists as a gas at ordinary conditions in RED.

7. Write the symbol of each element that is a solid at ordinary conditions in BLACK.

8. Write the symbol of each element that is a liquid at ordinary condition in BLUE.

9. Write the symbol of each element that is a man-made element as an outline. Example: Pm

10. Place the atomic number for each element above the symbol.

11. Use the following chart to color the periodic table.

Halogen blue

Noble gases yellow

Alkali metals purple

Alkaline earth metals red

Transition elements green

Chalcogens brown

Lanthanides orange

Actinides light blue

12. Outline the symbol’s box in dark green if it is RADIOACTIVE in its most common form.

1. Why do Li, Na, K, Rb, Cs, and Fr all react with Cl in a 1:1 ratio forming sub-

stances with similar properties?

2. Explain the method that John Newlands used to organize the elements.

3. What method did Dmitri Mendeleev use to arrange his periodic table?

4. Why did Mendeleev have gaps in his table? How did he use these gaps?

5. What was Henry Moseley’s contribution to the periodic table?

6. Explain the importance of valence electrons.

7. How is the electron configuration similar for each element in a group?

8. How is the electron configuration similar for each element in a period?
