ALKALI METALS

• Group IA (alkaline means basic)– Li– Na– K– Rb– Cs– Fr

Created by Tara L. Moore, MGCCC

ALKALINE EARTH METALS

• Group IIA– Be– Mg– Ca– Sr– Ba– Ra

Created by Tara L. Moore, MGCCC

HALOGENS

• Group VIIA (nonmetals, halogens means salt formers)– F– Cl– Br– I

Created by Tara L. Moore, MGCCC

NOBLE GASES

• Group VIII (nonmetals- rare gases)– He– Ne– Ar– Kr– Xe– Rn

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

Created by Tara L. Moore, MGCCC

Periods in a Periodic Table

• HORIZONTAL ROWS- elements in periods have properties that change progressively across the table

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)

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

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

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
