Periodic Table Worksheet 1. Where are the most active metals located? _______________________________________________________ 2. Where are the most active nonmetals located? ___________________________________________________ 3. As you go from left to right across a period, the atomic size ( decreases or increases ). 4. As you travel down a group, the atomic size ( decreases or increases ). 5. Elements in Group 1 are called? _____________________________________________________________________ 6. Elements in Group 2 are called? _____________________________________________________________________ 7. Elements in Group 3-­‐12 are called? _________________________________________________________________ 8. As you go from left to right across the periodic table, the elements go from ( metals / nonmetals ) to ( metals / nonmetals ) 9. Group 17 elements are called? _____________________________________________________________________ 10. Group 18 elements are called? _____________________________________________________________________ 11. Elements within a group have a similar number of _______________________________________________ 12. Elements in the periodic table are arranged according to their __________________________________. 13. An element with both metallic and nonmetallic properties is called a ___________________________. For the following physical and chemical properties, put a check in the appropriate column if it applies to a metal or a nonmetal. Property Metal Nonmetal Malleable Lustrous Gas at room temperature Metallic bonding Has more than 4 valence electrons Ductile Brittle Fill in the following paragraph. The modern periodic table, elements are listed by increasing _________________________________. Each box _________________________________ represents an _________________________________. A box contains the name, atomic number, _________________________________, and _________________________________ for the element. Vertical columns in the table are called _________________________________. Most elements in a column have the same number of _________________________________ in the outer energy level and have similar _________________________________. Horizontal rows in the table are called ________________________. The elements on the left side of the table are _________________________________. Groups 3 – 12 contain metals known as the _________________________________. Elements on the right side are _________________________________. Place the letter of each of the above elements next to its description to the right of the table. ________ An alkali metal ________An alkaline earth metal ________ An inactive gas ________ An active nonmetal ________ A semi-­‐metal Bohr Models For each element, write the total number of electrons on the line. Then color the correct number of
electrons for each orbit. Remember, fill the orbit closest to the nucleus first, but never exceed the number
each orbit can hold. Lewis Dot Diagrams Place the valence electrons as dots around each of the following elements. Na Be Al Si P Br Ne
