    All elements are classified into metals, non-metals and metalloids.
    Majority of the elements are Metals (metallic properties).
    Nonmetals have properties opposite those of the metals.
    Metalloids have properties similar to both metals and non-metals.

  Distinguishing luster (shine)      Non-lustrous, various colors      Can be shiny or dull
  Malleable and ductile              Brittle, hard or soft             Solids
  (flexible) as solids

  Metallic oxides are basic,         Nonmetallic oxides are acidic,    They can form alloys with
  ionic                              compounds                         other metals.
