12. TURN IN YOUR BELLRINGER!

13. December 8, 2011 AGENDA: 1 – Bell Ringer and Participation Log 3 – Check HW 4 – Notes – Elements and their properties 5 – Start Elements and their properties assignment Today’s Goal: Students will be determine the properties of metals, non- metals and metalloids.  Homework 1. SCIENCE FAIR!!! 2. Start to Study your notes for next week’s exam

14. Thursday, December 8 CHAMPS! C – Conversation H – Help A – Activity M – Materials and Movement P – Participation S – Success!!!

15. Thursday, December 8 Objective: Students will be determine the properties of metals, non-metals and metalloids. Bell Ringer: A) What is the identity of the element with the following electron configuration? 1s 2 2s 2 2p 6 3s 2 3p 1  Aluminum B) How many valence electrons does this atom have?  3s 2 3p 1 = 3 valence e - C) Would this atom form an anion or a cation?  +3 = cation

16. Elements and their Properties Ms. Barkume 12/8 Elements and their Properties Reminder = What are the 3 types of elements and their properties? On the periodic table Columns = groups/families = same valence electrons so same chemical properties Rows = periods = same energy level METALS Most common type of element Forms (+) cation Alkali and Alkali Earth metals are very reactive Metals are reactive Malleable (bendable) and ductile (become wire) Conduct electricity Shiny, lustre

17. Elements and their Properties Ms. Barkume 12/8 Elements and their Properties What are the 3 types of elements and their properties? Non-metals Form (-) anions  except hydrogen Dull, brittle solids or gases Do not conduct electricity Non-reactive in elemental form On the far right side of the P.T. Examples H, C, N, O, P, S Halogens (F, Cl, Br, I) Noble Gases (He, Ne, Ar, Kr, Xe, Rn)

18. Elements and their Properties Ms. Barkume 12/8 Periodic Trends aka Periodicity What are the 3 types of elements and their properties? Metalloids These elements have properties of both metals and non-metals Located along the staircase in the p-orbital Brittle, crushable solids Shiny, lustre Conducts electricity Examples: B, Si, As, Sb, Te, Po, At, Ge

19. Elements and their Properties Ms. Barkume 12/8 Periodic Trends aka Periodicity Describe the location of each element type on the periodic table.
