  1. Families on the Periodic Table

  2. Alkali Metals Elements Solids: Lithium Li Potassium K Sodium Na Rubidium Rb Cesium Cs Francium Fr

  3. Characteristics Soft Dull silver color Reacts w/ halogens to form salts Oxidation number = +1 Alkali Metals (cont.)

  4. Alkaline Earth Metals Elements Solids Beryllium Be Magnesium Mg Calcium Ca Strontium Sr Barium Ba Radium Ra

  5. Characteristics Soft Shiny silver color Found naturally as a compound Oxidation number = +2 Alkaline Earth Metals (cont.)

  6. Transition Metals Elements Solids All “D-block” elements Atomic numbers 21-30 39-48 57, 72-80 89, 104-112

  7. Characteristics Hard, tough & strong Good catalysts Multiple oxidation states Used for alloys Transition Metals (cont.)

  8. Other Metals Elements Solids Aluminum Al Gallium Ga Indium In Tin Sn Thallium Tl Lead Pb Bismuth Bi

  9. Characteristics Solids Opaque Color Oxidation numbers +3, +4, -3 Very malleable Other Metals (cont.)

  10. Metalloids Elements Solids Boron B Silicon Si Germanium Ge Arsenic As Antimony Sb Tellurium Te Polonium Po

  11. Characteristics Some shiny Some dull Some Malleable Some Brittle Multiple ox. #’s Has properties of both metals and nonmetals Metalloids (cont.)

  12. Gases Hydrogen H Nitrogen N Oxygen O Solids Phosphorus P Sulfur S Selenium Se Carbon C Non-Metals

  13. Characteristics Poor conductors Brittle Little to no metallic luster High ionization energy High electronegativity Gain electrons easily Multiple oxidation numbers Non-Metals (cont.)

  14. Solids Iodine I Astatine At Liquids Bromine Br Gases Fluorine F Chlorine Cl Halogens

  15. Halogens (cont.) • Only group in all 3 states of matter • Highly reactive w/ Alkali Metals & Alkaline Earth Metals • High electronegativity • Oxidation number = -1

  16. Noble Gases Elements Gases Helium He Neon Ne Argon Ar Krypton Kr Xenon Xe Radon Rn

  17. Noble Gases (cont.) • Non-reactive • Odorless • Tasteless • Colorless • Nonflammable • Oxidation number = 0

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

  19. Characteristics Most are manmade High luster High electrical conductivity Usually bonded to non-metals AKA: lanthanides & actinides Inner Transition Metals (cont.)
