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