Rose – Alkali Metals g. Light Green – Noble Gases c. Purple – Alkaline Earth Metals h. Brown - Halogens d. Red – Transition metals i. e. Light Blue – Other metals Dark Green – Other non-metals 11. Draw a DARK Red zig-zag line that separates metals from non-metals (surrounded with metalloids) 12. Above each Group, complete a Lewis Dot Structure a. Use an “X” in place of a element symbol for each dot structure b. Do NOT do any transition metals c. Remember to follow the ‘s’ and ‘p’ electron pairing rule 13. In TOP RIGHT corner of paper a. Write “ATOM SIZE (+)” b. Draw arrow pointing down the paper c. Draw another arrow across the paper 14. In TOP LEFT corner of paper a. Write “ATOM MASS(+)” b. Draw arrow pointing down the paper c. Draw another arrow across the paper 15. In BOTTOM LEFT corner of paper a. Write “ IONIZATION ENERGY (+)” b. Draw arrow pointing up the paper c. Draw another arrow across the paper 16. Title your table “PERIOD TABLE of the ELEMENTS” Periodic Table Worksheet Name_______________________________ Use your textbook to fill in the table below, summarizing the typical physical properties of metals and non- 1 metals. (The obvious one has been done!) METALS NON-METALS good conductors of heat and electricity poor conductors THE PERIODIC TABLE The Periodic Table shows the elements arranged in order of increasing Atomic Number. ROWS are called PERIODS : COLUMNS are called GROUPS (family). Groups contain elements with similar valence electron numbers, so have similar chemical properties. There are 8 main groups, 10 main transitional groups, and 14 inner transitional groups Periods contain elements share the same electron shell. There are 7 periods. 1. Define a family. ________________________________________________________________________ 2. What is a period? _______________________________________________________________________ 3. What period are the following elements in? 4. 5. a. He _________ c. Ge _________ e. Al _________ g. Bromine _________ b. Rb _________ d. Cs f. Mg _________ h. Gold _________ _________ What group are the following elements? a. Sulfur _________ b. Ca _________ e. Pb _________ g. Boron _________ c. Iodine _________ d. Fe _________ f. Mn _________ h. Tin _________ Number each group of four elements 1-4 in Atomic radii size (smallest=1; largest=4): a. Cesium _________ c. H _________ a. Al _________ c. Rn _________ b. Lead d. Ca _________ b. Fr _________ d. He _________ _________ 6. Which classification group is Hydrogen? Why? 7. Main group elements include all elements except _________________________________. Periodic Table Worksheet Name_______________________________ 8. What qualities do the Transition Metals have that is different from the rest of the metals and non-metals? 9. The most reactive metals are in the ______________________ group. 10. The most reactive non-metals are in the _______________________group. 11. Why are Alkaline Earth Metals less reactive than Alkali Metals? 12. Three Alkali metals and give two physical and two chemical similarities shown in this Group. NAME SYMBOL PHYSICAL SIMILARITY CHEMICAL SIMILARITY 1) 1) 2) 2) 13. Three Halogens and give two physical and two chemical similarities shown in this Group. NAME SYMBOL PHYSICAL SIMILARITY CHEMICAL SIMILARITY 1) 1) 2) 2) 14. Explain why helium atmosphere is used in welding rather than an oxygen rich atmosphere. 15. Explain why Halogens readily react with Alkali Metals to form salts? 16. Why is an iron alloy, such as steel, preferred over pure iron? 17. Explain why the exact size of an atom is difficult to determine. 18. Explain the decrease in atomic radii as you move across the period from Group1 to Group14. 19. Explain why the ionization energies tend to decrease down a group.
