A metal is a material that is usually hard, shiny, and has good electrical and thermal conductivity. Some examples of metals are aluminum, copper, iron , gold, lead, silver, uranium, and zinc.

The picture beside is showing some examples of metals.


Non-metals are the elements in groups 14-16 of the periodic table. Non-metals are not able to conduct electricity or heat . As opposed to metals, non-metallic elements are very brittle, and cannot be rolled into wires or as much or pounded into . The non-metals exist in two of the three states of matter at room temperature: gases and solids.The non-metals have no metallic luster, and do not reflect light.


  • A metalloid is a chemical element with properties in between, or that are a mixture of, those of metals and nonmetals. There is actually not a definition of a metalloid, nor is there complete a debate as to which elements are classified as which one is which.
