UNIT 1 M ATTER D AY 14 S EPTEMBER 20, 2016 Periodic Table Earth and Environmental Science

S EPTEMBER 20, 2016 S CIENCE STARTER : W HICH GROUP ON THE PERIODIC TABLE DO THE ALKALI METALS REACT WITH EASILY AND WHY ?

S EPT. 19, 2016 Plan for today: 1. Continue Periodic Table Lesson a. Notes b. Shading groups 2. Wrap-up

Essential Question How does atomic structure affect the physical and chemical properties of elements?

Homework: Due Friday (1) New wkbk pp (skip 91) Old wkbk pp (skip 92) (2) CFA on the periodic table is this Friday 9-23.

P ROPERTIES OF MATTER R E - QUIZ 5 th Period – Wednesday during Mav Time 6 th Period – Thursday during Mav Time

L ET ’ S CONTINUE NOTES ABOUT THE PERIODIC TABLE. G RAB YOUR YELLOW NOTES SHEET.

Y ESTERDAY WE LEARNED THAT THE ALKALI METALS ARE THE MOST REACTIVE GROUP ON THE PERIODIC TABLE. L ET ’ S WATCH JUST HOW REACTIVE THEY ARE WHEN THEY ARE PLACED IN WATER, ONE OF THE MOST STABLE, NEUTRAL SUBSTANCES THAT EXISTS. HTTPS :// WWW. YOUTUBE. COM / WATCH ? V =H V VU TPD K7 X W HTTPS :// WWW. YOUTUBE. COM / WATCH ? V =H V VU TPD K7 X W

W HAT DID WE LEARN ABOUT ALKALI METALS FROM THIS VIDEO ? L ET ’ S ADD IT TO THE YELLOW NOTES.

T RANSITION E LEMENTS (M ETALS ) All metals Coinage metals; common metals Mostly shiny, ductile, malleable, good conductors, solid (except Mercury) Some are more reactive than others Ex. Iron, copper, gold, nickel, silver

L ET ’ S S HADE THESE 3 GROUPS ON THE P. T. AND ADD IMPORTANT DETAILS. DO NOT SHADE HYDROGEN THE SAME COLOR AS THE ALKALI METALS. I T ISN ’ T A METAL. S O WHY IS IT IN GROUP 1 ON THE PERIODIC TABLE ?

L ET ’ S ADD INFO. ABOUT OTHER GROUPS TO OUR YELLOW NOTES.

P ROPERTIES OF THE T HREE M AJOR C ATEGORIES OF E LEMENTS 32. Non-Metals 1.Dull (no luster) 2.Brittle; not malleable or ductile 3.Low melting & boiling points 4.Poor conductors 5.Low density 6.Generally opposite properties to metals 7. Most are gases Carbon

P ROPERTIES OF THE T HREE M AJOR C ATEGORIES OF E LEMENTS 33. Metalloids 1.Border the stair step (zigzag) on the right side of the Table 2. Called semi- conductors (can sometimes conduct electricity) 3. Silicon is used in electronic devices 4. Properties of both metals & non-metals 5. Can be shiny or dull 6. Some are malleable and ductile, others are brittle 7. Mostly solid

S MART LESSON – LET ’ S FILL IN INFORMATION ABOUT THE OTHER GROUPS...\Unit 1 Matter \Periodic table groups slide with screenshade.notebook

L ET ’ S SHADE THE REMAINING GROUPS AND WRITE IMPORTANT DETAILS ABOUT EACH.

L ET ’ S WATCH A B RAINPOP VIDEO ABOUT THE P ERIODIC T ABLE. /periodictableofelements/
