REVIEW OF LAST CLASS January 30th

Summary: We had a standard opening. We went over Essential Element worksheet, took notes, signed up for Superhero element.

Answer the last class’s EQ which was: Essential Question: Identify characteristics of essential elements..

Topic/Objective: Name: Electrons Class/Period: Date: Feb 2, 2015 Essential Question: Identify traits of electrons

Tuesday January Standard: 7 Periodic Table Periodic Table II. Groups have similar properties. Group 1: Alkali Metals-Most reactive metals and the least dense metals –Floats on water Group 2: Alkaline Earth Metals-very reactive also but not as much as group 1 Group 3-12: Transition metals-very dense

Tuesday January Standard: 7 Periodic Table Periodic Table Group 17 Halogens –very reactive non metals. Group 18- Noble gases (inert gases)- unreactive nonmetals
