Periodic Table Groups 1. Color-code the following groups on your periodic table: -alkali group -alkaline group - transitional group -halogen group -noble gases -inner transitional group 2.Add the staircase (separates metals/non-metals.) 3.Place an asterisk by each metalloid. 4.Non-metals groups: Which group is most reactive and which is most stable? Explain how you know this. 5.Metal groups: Which group is most reactive and which is most stable? Explain how you know this. 6.Give an example of two elements that will form an ionic bond to reach stability. 7.Give an example of two elements that will form a covalent bond to reach stability. 8.What does each period on the periodic table symbolize for an atom? 9.What period and group is Bromine in? 10.a. What is electronegativity? b. What is the trend in electronegativity across a period and down a group on the periodic table.

Periodic Table Applications 1.Pick a representative element and a transitional element from your periodic table and answer the following qts. for each: a.What group is it in? b.Using electron configuration, validate the number of valence electrons it has. c.Would it participate in ionic and/or covalent bonding? Explain your answer. 2. Of the two elements you chose, which do you predict would have a greater electronegativity? Explain your answer.

Electronegativity and Chemical Bonding Do metals or non-metals have a greater electronegativity value?
15
Chemical Nomenclature Review with peers and place problems on Activ board we need to address:
