Types of Elements​: Metals

• ​An element that is a good conductor of heat and  electricity 

  At room temperature, most are solids 

  • Malleable- can be rolled or hammered into sheets 

  • Ductile- can be made into wire 

  Magnetic- attracted to magnets

​Types of Elements: Non-metals

• ​An element that is a poor conductor of heat and electricity

• Many are gases at room temperature 

• Some are solids: usually brittle, not malleable

​Types of Elements: Metalloids

• ​Sometimes called semimetals 

  An element that has some characteristics of both metals and non-metals 

  Appear along the staircase line 

  • B, Si, Ge, As, Sb, Te, At 

  • All are solids at room temperature 

  Less malleable then metals, but Less brittle than non-metals
