Review of Periodic Groups and Drawing Atoms Scavenger Hunt

1. You must list 1 adjective for each of the groups of representative elements.  Then, check http://www.shodor.org/unchem/basic/atom/ to check some of your answers and see if there is anything you can add. 

1. If Lithium reacts vigorously with water, name one other element that may also react strong with water and explain why you picked that element.

1. You will now attempt to learn electron dot diagrams (also known as Lewis Dot Structures).  Visit http://nobel.scas.bcit.ca/chem0010/unit3/3.3.2_Lewis.htm and
   1. Define valence electrons.
   2. Draw Bohr’s diagram for each of the elements in the first group displayed.  Is this how we drew them?  Explain what happens as you go down the periodic table in Group 1. 
   3. Compare and Contrast the elements in Groups 17 and 18 (7A and 8A) using the Bohr’s models.

1. If chlorine reacts strongly with sodium, would you expect the same from its next-door neighbor Argon?  Why or why not?

1. Define Lewis Electron Dot Symbols, then use that definition to write a dot diagram for K. 

1. Now click on the rules in gray for drawing Lewis Dot Structures.  After reviewing the rules, check your answer for K in question 5.  Then attempt to apply the rules to the following elements: Ca, Al, C, P, O, F, He, Ne, and Ar.  Do you see any patterns?  Check your answers below to see if you can draw these.  They weren’t that hard were they?

1. When you feel good about Dot Structures and Bohr’s Diagram, take a second to review isotopes (look left).  Pick an element and show me two isotopes similar to the example shown. 

1. Click at the bottom left on Problem sets 1, 2, and 3.  Complete the questions on your computer. 

1. If finished, use this website to review physical and chemical changes.  Try the problem set.

1. Tell the person next to you how happy you are that they are your partner.
