3. Created by Tara L. Moore, MGCCC ALKALI METALS Group IA (alkaline means basic) –Li –Na –K–K –Rb –Cs –Fr

4. Created by Tara L. Moore, MGCCC ALKALINE EARTH METALS Group IIA –Be –Mg –Ca –Sr –Ba –Ra

5. Created by Tara L. Moore, MGCCC HALOGENS Group VIIA (nonmetals, halogens means salt formers) –F–F –Cl –Br –I–I

6. Created by Tara L. Moore, MGCCC NOBLE GASES Group VIII (nonmetals- rare gases) –He –Ne –Ar –Kr –Xe –Rn

7. Created by Tara L. Moore, MGCCC Group or Families of the Periodic Table VERTICAL COLUMNS- elements in a group have similar chemical and physical properties

8. Created by Tara L. Moore, MGCCC Periods in a Periodic Table HORIZONTAL ROWS- elements in periods have properties that change progressively across the table

9. Created by Tara L. Moore, MGCCC Physical Properties of Metals High electrical conductivity that decreases with increasing temperature. High thermal conductivity. Metallic gray or silver luster Almost all are solids Malleable (can be hammered into sheets, etc.) Ductile (can be drawn into wires)

10. Created by Tara L. Moore, MGCCC Physical Properties of Nonmetals Poor electrical conductivity (except carbon in the form of graphite) Good heat insulators (except carbon in the form of diamonds) No metallic luster Solids, liquids or gases Brittle in solid state Non-ductile

11. Created by Tara L. Moore, MGCCC Chemical Properties of Metals Outer shells contain few electrons (usually 3 or fewer) Forms cations (positive ions) by losing electrons Form ionic compounds with nonmetals Solid state characterized by metallic bonding

12. Created by Tara L. Moore, MGCCC Chemical Properties of Nonmetals Outer shells contain four or more electrons Form anions (negative ions) by gaining electrons Form ionic compounds with metals and molecular (covalent) compounds with other nonmetals. Covalently bonded molecules; Noble gases are monatomic
