  1. Periodic Table Basics • Period • Row on the periodic table • Tells energy level • Principal Quantum Number Episode 402

  2. Number the periods 1 2 3 4 5 6 7 Episode 402

  3. Periodic Table Basics • Period • Row on the periodic table • Tells energy level • Principal Quantum Number • Family or Group • Columnon the periodic table • For columns 1-2and 13-18,the number in the one’s place represents number of valence electrons Episode 402

  4. Number columns and indicate # of valence electrons 1 18 1 2 13 17 2 3 3 12 4 5 6 7 Episode 402

  5. Periodic Table Basics • Metalloids • Have properties of both metals and non-metals • semiconductors • Border zig-zagline (except Al, which is a metal) Episode 402

  6. Mark the zig-zag border and label metalloids 1 18 1 2 13 17 B 2 Non-metals 3 3 12 Si 4 Ge As metals 5 Sb Te 6 Po At 7 Episode 402

  7. Solids, Liquids, or Gases 1 18 All other elements are solids. 1 H 2 13 17 He B N O F Ne 2 3 3 12 Si Cl Ar Br 4 Ge As Kr 5 Sb Te Xe 6 Hg Po At Rn 7 Episode 402

  8. ALKALI METALS Group 1 • Hydrogen is not a member, it is a non-metal • 1 electron in the outer shell • Soft and silvery metals • Very reactive, esp. with water • Conduct electricity http://www.youtube.com/watch?feature=player_embedded&v=6ZY6d6jrq-0 Episode 402

  9. ALKALINE EARTH METALS Group 2 • 2 electrons in the outer shell • White and malleable • Reactive, but less than Alkali metals • Conduct electricity http://www.youtube.com/watch?v=B2ZPrg9IVEo&feature=player_embedded Episode 402

  10. TRANSITION METALS Groups 3-12 • Good conductors of heat and electricity. • Some are used for jewelry. • The transition metals are able to put up to 32 electrons in their second to last shell. • Can bond with many elements to form a variety of compounds. Episode 402

  11. BORON FAMILY Group 13 • 3 electrons in the outer shell • Most are metals • Boron is a metalloid Episode 402

  12. CARBON FAMILY Group 14 • 4 electrons in the outer shell • Contains metals, metalloids, and a non-metal Carbon (C) Episode 402

  13. NITROGEN FAMILY Group 15 • 5 electrons in the outer shell • Can share electrons to form compounds • Contains metals, metalloids, and non-metals Episode 402

  14. OXYGEN FAMILY Group 16 • 6 electrons in the outer shell • Contains metalloids, and non-metals • Reactive Episode 402

  15. Halogens Group 17 • 7 electrons in the outer shell • All are non-metals • Very reactive are often bonded with elements from Group 1 http://www.youtube.com/watch?v=u2ogMUDBaf4&feature=player_embedded Episode 402

  16. Noble Gases Group 18 • Exist as gases • Non-metals • 8 electrons in the outer shell = Full • Helium (He) has only 2 electrons in the outer shell = Full • Not reactive with other elements Episode 402

  17. Rare Earth Metals • Some are Radioactive • The rare earths are silver, silvery-white, or gray metals. • Conduct electricity Lanthanides Actinides Episode 402
