Metalloids
Key Questions
-
Metalloids are unique because they have properties of both metals and non-metals.
For example, boron acts as a nonmetal when it reacts with sodium, but it acts as a metal when it reacts with fluorine.
Silicon has a metallic lustre, but it is a poor conductor and is brittle
Most metals have a characteristic lustre and are good conductors of heat and electricity.
Most metalloids have a metallic lustre but are poor conductors of heat and electricity.
Most nonmetals have a dull appearance and are poor conductors of heat and electricity.

The common classification for Metalloids are, possess some characteristics of metals and some of non-metals, semi-conductive, and are metallic lustre.
There are only seven classified elements:
- 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.

Not sure what your question is - what type of information do you want to learn about the metalloids?
The metalloids include the following elements: B, Si, Ge, As, Sb, Te, and Po.
I'd suggest visiting the website: http://www.ptable.com/
It has lots of information about these elements!
