3. Families of the Periodic Table:At the conclusion of our time together, you should be able to: Name each region of the Periodic Table Name each family of the Periodic Table List at least 3 characteristics of each family of the Periodic Table

4. Have you ever noticed that you tend to be attracted to someone kind of like you??

5. Periods in the Periodic Table 1 2 3 4 5 6 7

6. Regions of the Periodic Table

7. Metals • Extra electrons • Conductive • Malleable • Dense • Shiny • Ductile

8. Metalloids • Partly Conductive

9. Non-Metals • Desire Electrons • Not Conductive • Not Malleable • Dull

10. Groups in the Periodic Table Elements in groups (families) react in similar ways!

11. 15 Helpful Hints On The Lab Report from Mr. T’s Vast Lab Experience!!! Hint #14. No experiment is ever a complete failure, it can always serve as a bad example.

29. Gases (Hydrogen) Nitrogen Oxygen Solids Phosphorus Sulfur Selenium Carbon Other Non-Metals

30. Characteristics Non-metal qualities: dull, brittle, non-conductor, etc. High ionization energy High electronegativity Gain electrons easily Other Non-Metals (cont.)

32. Group 7A: The Halogens (salt makers) F, Cl, Br, I, At

33. Solids Iodine Astatine Liquids Bromine Gases Fluorine Chlorine Halogens

34. Halogens (cont.) • Characteristics • Only group with all 3 states of matter • Highly reactive w/ alkali metals & alkaline earth metals • High electronegativity • Non-metal qualities: dull, brittle, non-conductor, etc.

35. Noble (Inert) Gases Group 18 • S and/or P Orbitals Full • Very Non-reactive • Very Happy

36. XeOF4 Group 8A: The Noble (Inert) GasesHe, Ne, Ar, Kr, Xe, Rn • Lighter than air balloons • “Neon” signs • Very nonreactive because they have full electron levels

37. Noble Gases Elements Gases Helium Neon Argon Krypton Xenon Radon

38. Noble Gases (cont.) • Characteristics • Non-reactive • Odorless • Tasteless • Colorless • Nonflammable Non-metal qualities: dull, brittle, non-conductor, etc.

39. Inner Transition Metals Elements Solids All “F-block” elements Atomic numbers 58-71 90-103

40. Characteristics Most are manmade High melting points Metal qualities: shiny, good conductor, malleable, ductile Reactivity varies Usually bonded to non-metals AKA: lanthanides & actinides Inner Transition Metals (cont.)

41. New Elements Elements Atomic numbers 113 and on

42. Characteristics All are manmade Some will have metal qualities: shiny, good conductor, malleable, ductile Some will have non-metal qualities: dull, brittle, non-conductor, etc. Some will have qualities of both New Elements

43. Periodic Table Sing Along(sing to Battle Hymn of the Republic) • Mine eyes have seen the glory of the periodic chart • With its periods and columns it's a piece of genius art. • First he sorted by atomic mass, • t'wasMendeleev's first feat. • A search to organize. Chorus: • Periods - they go across, Families - they do go down • Groups are also known as columns, • The Periodic Chart!

44. Periodic Table Sing Along(sing to Battle Hymn of the Republic) • Some groups are given family names like • 1, 2, 7 and 8 • Alkali metals, reactive ones are on the far, far left. • Group 2 has the name of alkaline earth. • They're metals all the way. • These families act alike. Chorus: • Periods - they go across, Families - they do go down • Groups are also known as columns, • the Periodic Chart!

45. Periodic Table Sing Along(sing to Battle Hymn of the Republic) • The halogens, group 7 are a non-metallic clan • Group 8 seeks to be alone, acting as noble as they can • The transition, in the middle the most useful • atoms known • Form colored compounds too. Chorus: • Periods - they go across, Families - they do go down • Groups are also known as columns, • the Periodic Chart
