Properties of Metals, Metalloids, and Nonmetals

1
Properties of Metals, Metalloids, and Nonmetals
2
METALS NONMETALS

• Where are the metals and nonmetals on the PT?
• What are the properties of metals and nonmetals?
• What are metalloids?

3

• METALS LEFT SIDE OF PT
• METALLOIDS ALONG THE STAIRCASE (except
  Aluminum)
• NONMETALS RIGHT SIDE OF PT (except Hydrogen)

4
PROPERTIES OF METALS

• Physical Properties
• Solid at room temperature- exception Hg
• High density and melting point
• Good conductors of heat/electricity
• Metallic luster (shine)
• Malleable
• Ductile
• Chemical Properties
• Lose Electrons
• Corrode easily

5
METALLOIDS

• Properties and characteristics of both Metals and
  Nonmetals
• Along the staircase/steps of the Periodic Table
• Solids
• Can be shiny or dull
• Semi-Conductors of heat and electricity
• Ductile and Malleable

6
PROPERTIES OF NONMETALS

• Physical Properties
• Low density and melting point
• Not ductile
• No metallic luster
• Poor conductors of heat/electricity
• Brittle (breaks easily)
• Not malleable
• Chemical Properties
• Tend to gain electrons(makes negative ion)
