How can I classify metalloids?

The common classification for are, possess some characteristics of metals and some of non-metals, semi-conductive, and are metallic lustre.

There are only seven classified :

• Boron
• Silicon
• Germanium
• Arsenic
• Antimony
• Tellurium
• Polonium

The best way of determining if an unknown element is a Metalloid is by checking if any characteristics of metals and non-metals can be found, if both are then you most likely have a Metalloid element.
