Metals- • Lustrous (shiny)

• Good conductors of heat and electricity.

• High melting point.

• High density (heavy for their size)

• Malleable (can be hammered)

• Ductile (can be drawn into wires)

• Usually solid at room temperature (an exception is mercury)

• Opaque as a thin sheet (can't see through metals)

Non-metal- • High ionization energies.

• High electronegativities.

• Poor thermal conductors.

• Poor electrical conductors.

• Brittle solids—not malleable or ductile.

• Little or no metallic luster.

• Gain electrons easily.

• Dull, not metallic-shiny, although they may be colorful.

Metalloid-Are generally solids

  • Can be shiny or dull (luster)
  • May or may not be drawn into wire (ductile)
  • May or may not be hammered flat (malleable)
  • May or may not be brittle
  • Conduct heat and electricity better than nonmetals, but not as well as metals Tend to make good semiconductors
  • Have boiling points that are widely varied
  • Have melting points that are widely varied
  • Have densities that are widely varied

Metals are lustrous, malleable, ductile, good conductors of heat and electricity,Non-metals are brittle, dull, and poor conductors of heat and electricity,Metalloids they are shiny, brittle solids with intermediate to relatively good electrical conductivity and the electronic band structure of a semimetal or semiconductor.

What are Metal,Non-metal and Metalloids?

  • Metals are generally shiny, malleable, and hard. Metals are also good conductors of electricity.
  • Non-metals do not conduct heat or electricity very well.
  • Metalloids share characteristics of both metals and non-metals and are also called semimetals.
