  1. Elements Tara Midgett

  2. Group 1 Alkali Metals • Metals • Electrons in outer layer: 1 • Very reactive • Soft, color of silver, shiny, low density • Li ( Lithium), Na ( Sodium), K ( Potassium), Rb (Rubidium), Cs ( cesium), Fr (Francium)

  3. Group 2Alkaline- Earth Metals • Metals • Electrons in outer layer : 2 • Very reactive but less reactive then alkali metals • Color of silver, higher densities then alkali metals • Be ( Beryllium), Mg ( Magnesium), Ca ( Calcium), Sr (Strontium), Ba ( Barium), Ra ( Radium)

  4. Group 3-12Transition Metals • Metals • Electrons on outer layer: 1 or 2 • Less reactive the alkaline- earth metals • Shiny, good conductor, Higher density

  5. Group 13Boron Group • One metalloid and five metals • Electrons in outer layer: 3 • Reactive • Solid at room temperature • B (Boron), Al ( Aluminum), Ga( Gallium), In (Indium), Ti ( Thallium), Unt ( Ununtrium)

  6. Group 14Carbon Group • One nonmetal, two metalloids, and three metals • Electrons in outer layer: 4 • Varies in reactivity among the elements • Solid at room temperature • C ( Carbon) , Si ( Silicon), Ge ( Geranium), Sn( Tin), Pb (lead), Unq ( Ununquadium)

  7. Group 15Nitrogen Group • Two nonmetals, two metalloids and two metals • Electrons in outer layer: 5 • Varies in reactivity among the elements • Solid at room temperature ( except nitrogen) • N ( Nitrogen), P ( Phosphorus) , As ( Arsenic), Sb ( antimony), Bi ( Bismuth), Uup (Ununpentium)

  8. Group 16Oxygen Group • Three nonmetals, one metalloid and one metal • Electrons in outer layer: 6 • Reactive • Solid at room temperature except Oxygen • O ( Oxygen), S ( Sulfur), Se ( Selenium), Te ( Tellurium) , Po ( Polonium)

  9. Group 17Halogens • Nonmetals • Electrons in outer layer: 7 • Very reactive • Poor conductors, violent reactions with Alkali metals • F ( Fluorine), Cl ( Chlorine), Br ( B Bromine), I ( Iodine), At ( Astatine)

  10. Group 18Noble Gases • Nonmetals • Electrons in outer layer: 8 except helium, which has 2 • Unreactive • Colorless, odorless, gases at room temperature. • He ( helium), Ne (neon), Ar(Argon), Kr(Krypton), Xe(Xenon),Rn(radon)

  11. Hydrogen • Electrons in outer layer: 1 • Reactive • Colorless, Odorless, Low density • H(hydrogen)
