The Periodic Table
Following your study of this chapter, you should be able to
1. Briefly explain the significance of the atomic number of an element and its position
in the periodic table. Since Mendeleev did not know about atomic numbers, how
did he organize his periodic table?
2a. In the blank periodic table below identify the areas of the table that contain the
representative elements, transition metals, lanthanides and actinides.
b) In the blank periodic table below identify the areas of the table that contain the
alkali metals, alkaline earth metals, chalcogens, halogens and noble gases.
3. In the blank periodic table below identify the areas of the table that contain the
metals, nonmetals and metalloids.
4a. Identify some of the physical properties of the following metals..
b) List five important properties that distinguish metallic elements from nonmetallic
c) Explain how the metallic behavior changes going down a group and across a
d) Identify the physical properties of the following nonmetals.
e) List five important properties that distinguish nonmetallic elements from metallic
f) Explain how the nonmetallic behavior changes going down a group and across a
5. Correlate the tendency for an element to gain or lose electrons with its position in
the periodic table.
6. Define oxidation and reduction in terms of electron transfer among reacting
7. Correlate the tendency for an element to be oxidized or reduced with its position in
the periodic table.
8a. Write the general equation describing single replacement reactions.
b) Write the products formed when the following substances are mixed.
9a. Below is table showing the relative activities of several metals.
9b) Describe how the activity series is used to predict products of single replacement
c) Write the products formed when the following substances are mixed,
10. What kind (or kinds) of elements are typically found in compounds containing
ions? What kind (or kinds) of elements are typically found in compounds
11. Do metal oxides behave as acids, bases, or neutral compounds when added to
water? Do nonmetal oxides behave as acids, bases, or neutral compounds when
added to water?
12a. Explain why Group IA metals do not occur in nature as uncombined elements.
12b. Write the products formed when the following substances are mixed,
c) Describe the trend in melting point and density which occurs in the Group IA
13a. Describe the difference in reactivity of the Group IA and Group IIA elements with
b) Write the products formed when the following substances are mixed,
c) Describe the trend in melting point and density which occurs in the Group IIA
14. Aluminum is widely used in construction, yet it is ranked as an active metal in the
activity series. Suggest an explanation for this anomaly.
15. Describe some of the physical and chemical properties of hydrogen.
16. Describe some of the physical and chemical properties of the chalcogens.
17. Describe some of the physical and chemical properties of the halogens.
18. Describe some of the physical and chemical properties of the noble gases.
19a. How would you distinguish between the elements, oxygen, hydrogen, chlorine,
nitrogen and iodine using any combination of physical or chemical properties?
b) How would you distinguish between the elements, sulfur, sodium, magnesium,
aluminum and bromine using any combination of physical or chemical properties?
