PERIODIC TABLE REVIEW EXERCISE
Directions: The purpose of this exercise is to help you review what you have learned about the periodic
table. As you read each of the following questions, add the appropriate information to the blank
periodic table and record your answers in the space provided on this worksheet.
1. How are the elements arranged on the periodic table?
2. What are the horizontal rows called? How many are there? Number them on your periodic table.
3. What are the vertical columns called? How many are there? Number them on your periodic table.
4. What is the relationship between all the elements in a period?
5. What element would be in period 4, family 9? Place this element on your period table. Add to the square
the atomic number, the atomic mass and the electron configuration.
6. What is the relationship between the electron configurations of every element in a family?
7. What are the transition elements? Where are they found on the period table? Label them.
8. Label the s block of elements. Label the p block of elements. Label the d block of elements. Label the f
block of elements.
Why is there no g or h block of elements?
Why is it called the s block?
Why is it called the p block?
Why is it called the d block?
Why is it called the f block?
9. Where are the lanthanoids? Label this group on the periodic table. Why are they called this?
10. Where are the actinoids? Label this group on the periodic table. Why are they called this?
11. As you go from top to bottom of a family what happens to the electrons possessed by that element?
12. Color the alkali metals yellow.
13. Color the alkaline earth metals green.
14. Color the nitrogen family orange.
15. Color the oxygen family purple.
16. Color the halogens blue.
17. Color the noble gases red.
18. Use arrows to indicated the following trends on the periodic table: ionization energy, electronegativity,
atomic radius, and the ionic radius. Draw the arrow to indicate an increase. Label each arrow.
19. Draw the line on the periodic table indicating the separation of the metals from the nonmetals. Label the
metals and nonmetals.
20. With your pencil, lightly shade in the blocks on the periodic table that fall into the group known as
metalloids or semimetals. Write in the chemical symbol of each of these elements in the proper block.
Answers:
1. The elements on the periodic table are arranged in order by increasing atomic number.
2. Horizontal rows are called periods. There are 7 periods.
3. Vertical columns are called groups or families. There are 18 groups.
4. The elements that are related in a period have the same valence shell..
5. Cobalt
6. They have the same number of valence electrons.
7. These elements are characterized by addition of electrons to d sublevels.
8. There is no g or h block because no element has electrons in these sublevels when the electrons are in
their ground state. The s block consists of elements that are filling their s sublevel. The p block has
elements that are filling the p sublevels. The d block has elements that are filling the d sublevels.
The f block has elements that are filling the f sublevels.
9. The lanthanoids are a series of transition elements within period 6 of the periodic table characterized
by successive filling of the 4f sublevel.
10. The actinoids are a series of transition elements within period 7 of the periodic table characterized by
successive filling of the 5f sublevel.
11. The valance electrons are found in the next higher energy level as you go down a family.
