What do all the elements in that portion have in common? Questions: 1.Describe the reasoning you used to arrange the cards. 2. How did you decide on a name for the groups? 3. If you discovered an unknown element, how would the element’s physical properties allow you to determine position of the element in your arrangement? EQ: What information can be gathered from the periodic table?

September 16, 2015 AGENDA 8.5 C Interpret the arrangement of the Periodic Table, including groups and periods, to explain how properties are used to classify elements. 6.6A compare metals, nonmetals and metalloids using physical properties such as luster, conductivity or malleability. 1 Starter 2.

Practice: Make a Chart MetalsNon-metalsMetalloids

Metals 1.Malleable (easily shaped) 2.Has Luster (Shiny) 3.Good conductor of heat 4.Good conductor of electricity 5.Some metals are magnetic

Non-metals 1.Brittle ( broken easily) 2.No Luster (not shiny) 3.Poor conductor of heat (insulator) 4.Poor conductor of electricity 5.No nonmetals are magnetic

Metalloids 1.The properties of metalloids are between metals and nonmetals. 2.Most like nonmetals- both chemically and physically. (Brittle, poor heat conductor) 3.They conduct electricity, but not as well as metals (semiconductors).

Application/ Connection With your partner, sort the element cards into metals, nonmetals, and metalloids. When finished, create a chart and write this information in your journal.
