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.

Chemical Nomenclature

Electronegativity Electronegativity: The degree of attraction one atom has towards another atom’s valence electron in a compound. O H H

Electronegativity and Chemical Bonding Do metals or non-metals have a greater electronegativity value?

Chemical Nomenclature Review with peers and place problems on Activ board we need to address:

Covalent Compounds Nomenclature: Prefixes One Two Three Four Five Six Seven Eight Nine Ten

Homework: Polar vs. Non-Polar Distinguish between polar and non-polar compounds with a Venn diagram. Classify each compound from the bell ringer as either ionic, polar, or non-polar by calculating their electronegativity differences.
