Use the blank periodic table to complete questions 1-7. Information may be obtained from textbooks, reference books or the internet. www.ptable.com is an excellent resource. Sample: 1. Write the symbol, the atomic number and the atomic weight (rounded to one IA decimal point) for each element in the appropriate box. Do not write the name. 1 G 1 2. Write the numbers 1 through 18 and the Roman numerals and the letters A or B at the IIA top of each column. (Hint: Check the periodic table on the wall at the front of the room) H 2 1.0 3. Write a small capital “L” in each box for an element that is a liquid at room temperature. 3 4 Li Be 4. Write a small capital “G” in each box for an element that is a gas at room temperature. 6.9 9.0
5. Write a small capital “M” in each box for an element that is a metalloid (semimetal).
6. Locate the "stair-step" line that separates the metals from the nonmetals and draw it on your periodic table.
7. Use colored pencils to color each of the regions on the periodic table that corresponds to a specific collection of elements. It doesn't matter which color you choose, just be sure to include a key on your periodic table so that you can tell which color goes with which group. a. alkali metals Be careful! There are no periodic tables in any of the b. alkaline earth metals textbooks in this classroom which are colored according c. transition metals to these instructions. When done correctly, there will d. halogens three uncolored columns. e. chalcogens f. inert gases (also known as noble gases) g. rare-earth metals (also known individually as the lanthanides and actinides or the inner transition metals) Chemistry Worksheet Date ______Period _ Name ______
CW PERTAB getting to know the PT 093011.DOC Getting to Know the Periodic Table Study Guide Page 2 Instructions: Answer the following questions on notebook paper.
1. What is meant by the term period? 2. What is meant by the term group? 3. List the names of the seven groups of elements on the periodic table. 4. Tell what to look for on the periodic table to identify the representative elements. 5. Tell what to look for on the periodic table to identify the transition metals. 6. List the names and symbols of the elements that are liquids at room temperature and pressure. 7. List the names and symbols of the elements that are gases at room temperature and pressure. 8. List the names and symbols of the elements that are metalloids and tell why they are called that. 9. List the names and symbols of the inert gases and tell why they are also called noble gases? 10. What information about an atom does the atomic number give us? 11. List at least three properties of metals. 12. List at least three properties of nonmetals 13. Find the two elements that are the most important semiconductors. (Hint: One is named for a hypothetical valley, the other for the country where the Bunsen burner was perfected.) 14. Compare the chemical reactivity of alkali metals, alkaline earth metals and inert gases. 15. What is the significance of the term periodic as applied to the periodic table? 16. Doberiener found several sets of triads. Give three of these sets of three elements. 17. Pick one triad and do the calculations which demonstrate why it is a Doberiener triade. 18. Relate octaves in music to Newlands’s law of octaves. 19. Describe two decisions made by Mendeleev which make his periodic table superior to Lothar Meyer’s? 20. What important change came to the periodic table because of the work of Henry Mosley? 21. How did the periodic table change because of the work of Glenn Seaborg? 22. Would the undiscovered element with an atomic number of 115 to be a metal or a nonmetal? 23. Consider the element with an atomic number of 118. Predict something about its chemical reactivity.
