How can I classify metalloids?

Answer 1

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.

Metalloids can be classified based on their intermediate properties between metals and nonmetals. Common methods include using physical properties like electrical conductivity, melting points, and appearance, or considering chemical properties such as their ability to form alloys or exhibit acidic or basic behavior.
